btrfs_setxattr_trans() is called by 5 functions as below and all of them
do updates. None of them would be roun on a read-only root.
So its ok to remove the readonly root check here as it's a high-level
conditon.
1.
__btrfs_set_acl()
btrfs_init_acl()
btrfs_init_inode_security()
2.
__btrfs_set_acl()
btrfs_set_acl()
3.
btrfs_set_prop()
btrfs_set_prop_trans()

btrfs_ioctl_setflags() btrfs_xattr_handler_set_prop()
4.
btrfs_xattr_handler_set()
5.
btrfs_initxattrs()
