gve: Fix GFP flags when allocing pages
[ Upstream commit a92f7a6feeb3884c69c1c7c1f13bccecb2228ad0 ]
Use GFP_ATOMIC when allocating pages out of the hotpath,
continue to use GFP_KERNEL when allocating pages during setup.
GFP_KERNEL will allow blocking which allows it to succeed
more often in a low memory enviornment but in the hotpath we do
not want to allow the allocation to block.
Fixes: f5cedc84a30d2 ("gve: Add transmit and receive support")
