gallium: fix type size in z24_unorm_packed_pack_z_32unorm

Browse source 
util_format_z24_unorm_packed_pack_z_32unorm was accidentally writing
48-bits instead of 24 since it used a 16-bit integer pointer instead of
an 8-bit pointer. This could cause a segfault if the function was used,
but it is currently unused.

Fixes: 18f352090d ("util/format: Add a Z24_UNORM_PACKED format")
