Description

Adjust function definitions in ufs_dirhash.c to avoid clang 15 warnings

With clang 15, the following -Werror warnings are produced:

sys/ufs/ufs/ufs_dirhash.c:1303:16: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
ufsdirhash_init()
               ^
                void
sys/ufs/ufs/ufs_dirhash.c:1319:18: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
ufsdirhash_uninit()
                 ^
                  void

This is because ufsdirhash_init() and ufsdirhash_uninit() are declared
with (void) argument lists, but defined with empty argument lists. Make
the definitions match the declarations.
