net: libwx: fix the creation of page_pool
commit 85720e04d9af0b77f8092b12a06661a8d459d4a0 upstream.
'rx_ring->size' means the count of ring descriptors multiplied by the
size of one descriptor. When increasing the count of ring descriptors,
it may exceed the limit of pool size.
[ 864.209610] page_pool_create_percpu() gave up with errno -7
[ 864.209613] txgbe 0000:11:00.0: Page pool creation failed: -7
Fix to set the pool_size to the count of ring descriptors.
