c/r: prctl: fix build error for no-MMU case
Commit 1ad75b9e1628 ("c/r: prctl: add minimal address test to
PR_SET_MM") added some address checking to prctl_set_mm() used by
checkpoint-restore. This causes a build error for no-MMU systems:
kernel/sys.c: In function 'prctl_set_mm':
kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function)
The test for mmap_min_addr doesn't make a lot of sense for no-MMU code
as noted in commit 6e1415467614 ("NOMMU: Optimise away the
{dac_,}mmap_min_addr tests").
This patch defines mmap_min_addr as 0UL in the no-MMU case so that the
compiler will optimize away tests for "addr < mmap_min_addr".
