Andreas Kling 94f287b1c0 Kernel: Unmap non-readable pages 
This was caught by running all crash tests with "crash -A".
Basically, non-readable pages need to not be mapped *at all* so that
a "page not present" exception is provoked on access.

Unfortunately x86 does not support write-only mappings, so this is
the best we can do.

Fixes #1336.
