compiler: Make ubi/ubifs compile with its unused variables 

Not sure why these were missing but they are very much needed to
compile the ubi code.

Fixes:
| drivers/mtd/ubi/attach.c:808:2: warning: parameter names (without types) in function declaration
|   long long uninitialized_var(ec);
|   ^~~~
| drivers/mtd/ubi/attach.c:847:3: error: 'ec' undeclared (first use in this function)
|    ec = UBI_UNKNOWN;
|    ^~
