staging: qlge: Refill rx buffers up to multiple of 16
Reading the {s,l}bq_prod_idx registers on a running device, it appears that the adapter will only use buffers up to prod_idx & 0xfff0. The driver currently uses fixed-size guard zones (16 for sbq, 32 for lbq - don't know why this difference). After the previous patch, this approach no longer guarantees prod_idx values aligned on multiples of 16. While it appears that we can write unaligned values to prod_idx without ill effects on device operation, it makes more sense to change qlge_refill_bq() to refill up to a limit that corresponds with the device's behavior.
