mmc: block: Avoid uninitialized warning in mmc_blk_issue_discard_rq()
With gcc-4.1.2:
mmc/core/block.c: In function ‘mmc_blk_issue_discard_rq’:
mmc/core/block.c:1150: warning: ‘arg’ may be used uninitialized in this function
mmc/core/block.c:1150: warning: ‘nr’ may be used uninitialized in this function
mmc/core/block.c:1150: warning: ‘from’ may be used uninitialized in this function
While this is a false positive, it can be avoided easily by jumping over
the checks for "err" that are always false.
