The driver vtables are read-only structures. This patch declares them as
'const' allowing the compiler to (optionally) put them in the RELRO
section. RELRO pages may be marked as read-only by the linker after
the relocations have been done ensuring that they aren't inadvertently
or maliciously altered at runtime.
QMI_UIM_GET_CARD_STATUS is retried in more error cases
when trying to get password type.
In case of failure, driver report an error instead of
OFONO_SIM_PASSWORD_INVALID. This avoids a crash.
Use right slot and application to get card status, PIN status and PIN
retries. Without this patch, SIMs where selected application and slot
numbers are different are not detected.

Command read_file_info on MC7304 always fails.
Using qmicli or AT command, I am able to read file info.
Qmicli command is:
qmicli -d /dev/cdc-wdm0 --uim-get-file-attributes=0x3f00,0x7fff,0x6fad
[(null)] Successfully got file '/dev/cdc-wdm0' attributes from the UIM:
Card result:

SW2: '0x00'

After a check of parameters sent by qmimodem driver and qmicli,
the only difference is on parameter "Session Information".
Session type sent by qmimodem driver is 'Card on slot 1'.
Session type sent by qmicli command is 'primary-gw-provisioning'.
Changing session type in qmimodem driver fixed problem (on this modem).
Comparing with what is done by qmili command
Retry command QMI_UIM_GET_CARD_STATUS during query_passwd_state if a
temporary error status has been detected.
This happens with a MC7430 modem when query_passwd_state is called just
after PIN is entered.
Password state and number of retries asked to modem using
QMI_UIM_GET_CARD_STATUS command rather than remembered after initial
QMI_UIM_GET_CARD_STATUS command.
Add read_imsi feature to qmimodem sim driver.
This is based on DMS service.
On MC7430, this is mandatory to be able to use this driver for GPRS
connection because reading IMSI via EF reads fails.
