	src/sys/miscfs/genfs: layer_vnops.c
	src/sys/uvm: uvm_pager.h

Log Message:
define a pager flag PGO_RECLAIM, similar to FSYNC_RECLAIM, and use it
to skip unnecessary flushing when layered file system vnodes are recycled.
this also prevents a deadlock with the dodgy LFS putpages routine.
fixes the non-LFS part of PR 36150.
