new 8a2b3b0492d fs/rpmsgfs: carry 32-bit uid and gid
8a2b3b0492d is described below
commit 8a2b3b0492dd020ba11162d750348e1053155b34

fs/rpmsgfs: carry 32-bit uid and gid
uid_t and gid_t are unsigned int, but struct rpmsgfs_stat_priv_s
carries them as int16_t. An id above 32767 is truncated on both the
chown and the stat path, so chown(path, 40000, ...) through rpmsgfs
sets the owner to 4294941760 on the server and stat() reports that.
Widen both fields to uint32_t. This changes the layout of the stat
and chstat messages, so the client and the server must be updated
together.
