i2c: octeon: remove unused signal handling
'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.
