net/sonic: Use MMIO accessors
[ Upstream commit e3885f576196ddfc670b3d53e745de96ffcb49ab ]
The driver accesses descriptor memory which is simultaneously accessed by
the chip, so the compiler must not be allowed to re-order CPU accesses.
sonic_buf_get() used 'volatile' to prevent that. sonic_buf_put() should
have done so too but was overlooked.
