 Fix a bug introduced by me in 1.214 where unmanaged mappings would be
 affected by calls to pmap_page_protect which is wrong.  Now PV_KENTER
 mappings are left intact.
 Thanks to chuq for spotting my mistake and reviewing this diff.
 Thanks to everyone who tested it as well.
 Fix PR/51288 reproducable panic on evbmips64-eb (erlite)
 pmap_page_remove from the previous change neglected to terminate the pv
 list correctly when it started with an initial unmanaged mapping and
 subsequent managed mappings.  Fix this.
 Fix MIPS3_NO_PV_UNCACHED alias handling by looping through the pv_list
 looking for bad aliases and removing the bad entries.  That is, revert
 to the code before the matt-mips64 merge.
 Additionally, fix the pmap_update call to not use the (recently
   removed/freed) pv for the pmap_t.
 Fixes the following two PRs
 PR/49903: Panic during installation on WorkPad Z50 (hpcmips) whilst uncompressing base.tgz
 PR/51226: Install bug for hpcmips NetBSD V7 using FTP Full installation
