vfs_glusterfs: Do not use glfs_fgetxattr() for SMB_VFS_GET_REAL_FILENAME_AT
glfs_fgetxattr() or generally fgetxattr() will return EBADF as dirfsp
here is a pathref fsp. GlusterFS client log had following entries
indicating the error:
W [MSGID: 114031] [client-rpc-fops_v2.c:993:client4_0_fgetxattr_cbk] \
0-vol-client-0: remote operation failed. [{errno=9}, {error=Bad file descriptor}]
Therefore use glfs_getxattr() only for implementing get_real_filename_at
logic.
