Fedor Pchelkin 76a10fc65a ksmbd: free ppace array on error in parse_dacl ...

commit 8cf9bedfc3 upstream.

The ppace array is not freed if one of the init_acl_state() calls inside
parse_dacl() fails. At the moment the function may fail only due to the
memory allocation errors so it's highly unlikely in this case but
nevertheless a fix is needed.

Move ppace allocation after the init_acl_state() calls with proper error
handling.
