Avoid clearing EXEC permission bit when setting the page RW on ARMv6/v7

When emulating modified bit the executable attribute was cleared by
mistake when calling pmap_set_prot(). This was not a problem before
changes to ref/mod emulation since all the pages were created RW basing
on the "prot" argument in pmap_enter(). Now however not all pages are RW
and the RW permission can be cleared in the process.

Added proper KTRs accordingly.
