net: use the new dev_page_is_reusable() instead of private versions

mainline inclusion
from mainline-v5.12-rc1-dontuse
commit a79afa78
category: feature
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a79afa78e625e4dbe0e07c70929d477ba3386e45



----------------------------------------------------------------------

Now we can remove a bunch of identical functions from the drivers and
make them use common dev_page_is_reusable(). All {,un}likely() checks
are omitted since it's already present in this helper.
Also update some comments near the call sites.
