linux-user: assert that target_mprotect cannot fail
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.
