ceph: use CEPH_MDS_OP_RMXATTR request to remove xattr
Setxattr with NULL value and XATTR_REPLACE flag should be equivalent to removexattr. But current MDS does not support deleting vxattrs through MDS_OP_SETXATTR request. The workaround is sending MDS_OP_RMXATTR request if setxattr actually removs xattr. Signed-off-by: Yan, Zheng <zyan@redhat.com>
