fs/file: more unsigned file descriptors

Propagate unsignedness for grand total of 149 bytes:

$ ./scripts/bloat-o-meter ../vmlinux-000 ../obj/vmlinux
add/remove: 0/0 grow/shrink: 0/10 up/down: 0/-149 (-149)
function                                     old     new   delta
set_close_on_exec                             99      98      -1
put_files_struct                             201     200      -1
get_close_on_exec                             59      58      -1
do_prlimit                                   498     497      -1
do_execveat_common.isra                     1662    1661      -1
__close_fd                                   178     173      -5
do_dup2                                      219     204     -15
seq_show                                     685     660     -25
__alloc_fd                                   384     357     -27
dup_fd                                       718     646     -72

It mostly comes from converting "unsigned int" to "long" for bit operations.
