[RFC PATCH 1/4] fs/fs_parse: add back fsparam_u32hex

[Eric Sandeen <sandeen@redhat.com>]

296b67059 removed fsparam_u32hex because there were no callers
(yet) and it didn't build due to using the nonexistent symbol
fs_param_is_u32_hex.

fs/9p will need this parser, so add it back with the appropriate
fix (use fs_param_is_u32).
