pNFS: rework pnfs_generic_pg_check_layout to check IO range

Browse Source 
All callers of pnfs_generic_pg_check_layout() also want to do a call to
check that the layout's range covers the IO range. Merge the functionality
of the pnfs_generic_pg_check_range() into that of
pnfs_generic_pg_check_layout().
