rbd: support timeout in rbd_wait_state_locked()
currently, the rbd_wait_state_locked() will wait forever if we
can't get our state locked. Example:
rbd map --exclusive test1 --> /dev/rbd0
rbd map test1 --> /dev/rbd1
dd if=/dev/zero of=/dev/rbd1 bs=1M count=1 --> IO blocked
To avoid this problem, this patch introduce a timeout design
in rbd_wait_state_locked(). Then rbd_wait_state_locked() will
return error when we reach a timeout.
This patch allow user to set the lock_timeout in rbd mapping.
