Mark Johnston 01cef4caa7 Remove page locking from pmap_mincore(). 
After r352110 the page lock no longer protects a page's identity, so
there is no purpose in locking the page in pmap_mincore().  Instead,
if vm.mincore_mapped is set to the non-default value of 0, re-lookup
the page after acquiring its object lock, which holds the page's
identity stable.

The change removes the last callers of vm_page_pa_tryrelock(), so
remove it.
