[PATCH 6/6] mountd: Use unsigned for filesystem type magic constants

[Patrick Steinhardt <ps@xxxxxx>]

The filesystem type magic constants are all unsigned integers, but we
declare them as signed ones. This may cause a compiler warning when
comparing our own signed magic constants with the unsigned ones return
by statfs64(3).

Fix the issue by uniformly usign unsigned types.
