[PATCH V2] libcfs: Fix a sleep-in-atomic bug in cfs_wi_deschedule

The driver may sleep under a spin lock, and the function call path is: cfs_wi_deschedule (acquire the lock by spin_lock) LASSERT lbug_with_loc libcfs_debug_dumplog schedule and kthread_run --> may sleep To fix it, all "LASSERT" is placed out of the spin_lock and spin_unlock. S
