ixgbe: Don't call kmap() on page allocated with GFP_ATOMIC

Browse source

Pages allocated with GFP_ATOMIC cannot come from Highmem. This is why
there is no need to call kmap() on them.

Therefore, don't call kmap() on rx_buffer->page() and instead use a
plain page_address() to get the kernel address.
