Björn Töpel 1beb7830d3 ice: avoid premature Rx buffer reuse 
The page recycle code, incorrectly, relied on that a page fragment
could not be freed inside xdp_do_redirect(). This assumption leads to
that page fragments that are used by the stack/XDP redirect can be
reused and overwritten.

To avoid this, store the page count prior invoking xdp_do_redirect().

Fixes: efc2214b6047 ("ice: Add support for XDP")
