sparc: fix mis-use of __kernel_{uid,gid}_t in uapi/asm/stat.h
Commit 31a088b664d6 ("sparc: add asm/stat.h to UAPI compile-test
coverage") converted as follows:
uid_t --> __kernel_uid_t
gid_t --> __kernel_gid_t
It changed the field widths of struct stat because Sparc uses 16-bits for
___kernel_{uid,gid}_t as in arch/sparc/include/uapi/asm/posix_types.h.
The safe replacements across all architectures are:
uid_t --> __kernel_uid32_t
gid_t --> __kernel_gid32_t
as defined in include/linux/types.h.
A similar issue was reported for the android binder. [1]
