Anand Jain 353c2ea735 btrfs: remove redundant readonly root check in btrfs_setxattr_trans 
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()
    btrfs_xattr_security_init()
      btrfs_init_inode_security()
