When the insmntque() in the pfs_vncache_alloc() fails, vop_reclaim calls
pfs_vncache_free() that removes pvd from the list, while it is not yet
put on the list.

Prevent the invalid removal from the list by clearing pvd_next and
pvd_prev for the newly allocated pvd, and only move pfs_vncache list
head when the pvd was at the head.
