'commit 2637e5fd232d ("i2c: octeon: Fix i2c fail problem when a process is
terminated by a signal")' removed the wait_event_interruptible_timeout to
prevent half/mixed i2c messages from being sent/recievd but forgot to
drop the signal handling case in the return handling. This just removes
this dead code. While at it the return variable is adjusted to the type
expected.

V2: Thanks to Wolfram Sang <[email protected]> for clarifying the intent
(and how I should have found this by properly checking the git log).
Patch was compile tested with cavium_octeon_defconfig
(implies CONFIG_I2C_OCTEON=y)
Patch is against 4.1-rc7 (localversion-next is -next-20150611)
