Rafal Jaworowski ec34d19b9d Simplify and clean up pmap_clearbit() 
There is no need for calling vm_page_dirty() when clearing "modified" flag as
it is already set for that page in pmap_fault_fixup() or pmap_enter() thanks
to "modified" bit emulation.

Also, there is no need for checking PTE "referenced" or "writeable" flags.  If
there is a request to clear a particular flag we should just do it.
