[PATCH] I2C: replace schedule_timeout() with msleep_interruptible() in i2c-ibm_iic.c

Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected. Remove the unnecessary
set_current_state() following the if, as schedule_timeout() [and thus,
mlseep_interruptible()] is guaranteed to return in TASK_RUNNING.
