m68k/sun3: Kill pte_unmap() warnings
Since commit 31c911329e048b715a1dfeaaf617be9430fd7f4e ("mm: check the argument
of kunmap on architectures without highmem"), we get lots of warnings like
arch/m68k/kernel/sys_m68k.c:508: warning: passing argument 1 of ‘kunmap’ from incompatible pointer type
As m68k doesn't support highmem anyway, open code the calls to kmap() and
kunmap() (the latter is a no-op) to kill the warnings, like is done on most
other architectures without CONFIG_HIGHPTE.
