reiserfs: don't acquire lock recursively in reiserfs_acl_chmod

reiserfs_acl_chmod() can be called by reiserfs_set_attr() and then take
the reiserfs lock a second time.  Thereafter it may call journal_begin()
that definitely requires the lock not to be nested in order to release
it before taking the journal mutex because the reiserfs lock depends on
the journal mutex already.

So, aviod nesting the lock in reiserfs_acl_chmod().
