ext4: add support for 32-bit default reserved uid and gid values

Browse source

Support for specifying the default user id and group id that is
allowed to use the reserved block space was added way back when Linux
only supported 16-bit uid's and gid's.  (Yeah, that long ago.)  It's
not a commonly used feature, but let's add support for 32-bit user and
group id's.
