ceph: handle cap import atomically
cap import messages are processed by both handle_cap_import() and handle_cap_grant(). These two functions are not executed in the same atomic context, so they can races with cap release. The fix is make handle_cap_import() not release the i_ceph_lock when it returns. Let handle_cap_grant() release the lock after it finishes its job. Signed-off-by: Yan, Zheng <zheng.z.yan@intel.com>
