This patch fixes following compile time warnings.
drivers/mmc/card/block.c: In function ‘mmc_blk_issue_rq’:
drivers/mmc/card/block.c:828:18: warning: ‘arg’ may be used uninitialized in this function [-Wun initialized]
drivers/mmc/card/block.c:794:25: note: ‘arg’ was declared here
drivers/mmc/card/block.c:827:6: warning: ‘nr’ may be used uninitialized in this function [-Wunin itialized]
drivers/mmc/card/block.c:794:21: note: ‘nr’ was declared here
drivers/mmc/card/block.c:827:6: warning: ‘from’ may be used uninitialized in this function [-Wun initialized]
drivers/mmc/card/block.c:794:15: note: ‘from’ was declared here
If the code follows the labels 'out' and 'retry', then we get
to situation when these variables are used uninitialized.

The patch is rebased on v3.2-rc2.
I don't have much idea on what should be the default value
for these variables. The fixes are provided just to do away
with the compile time warnings.
