bsd-user/mmap.c: assert that target_mprotect cannot fail
Similar to the equivalent linux-user change 86abac06c14. All error
conditions that target_mprotect checks are also checked by target_mmap.
EACCESS cannot happen because we are just removing PROT_WRITE. ENOMEM
should not happen because we are modifying a whole VMA (and we have
bigger problems anyway if it happens).
Fixes a Coverity false positive, where Coverity complains about
target_mprotect's return value being passed to tb_invalidate_phys_range.
