mountd: fix --manage-gids hang due to int/uint bug

A uid or gid should be represented as unsigned, not signed.

The conversion to signed here could cause a hang on access by an unknown
user to a server running mountd with --manage-gids; such a user is
likely to be mapped to 232-1, which may be converted to 231-1 when
represented as an int, resulting in a downcall for uid 231-1, hence the
original rpc hanging forever waiting for a cache downcall for 232-1.
