'commit d295a86eab20 ("i2c: mv64xxx: work around signals causing I2C
transactions to be aborted")' removed the wait_event_interruptible_timeout
to prevent half/mixed i2c messages from being sent/received but forgot to
drop the signal received cases in the return handling. This just removes
this dead code and simplifies the error message as "time_left" only can be
0 here and thus it conveys no additional information.

Patch was compile tested with multi_v7_defconfig
(implies CONFIG_I2C_MV64XXX=y)
Patch is against 4.1-rc7 (localversion-next is -next-20150611)
