staging: mt7621-eth: Fix compilation error

Browse source 
Fix the following comilation error by making sure that "phy_ring_head" is
defined as "dma_addr_t" and change "phy_ring_tail" to match it as both
should be "dma_addr_t".

error: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
