net/bnxt: disable end of packet padding for Rx

Browse Source 
Testing has shown that the packet forwarding rate for packet sizes
that are not a multiple of the cache line size is reduced when the
DMA size is padded to a multiple of the cache line size. Improve
performance for these packet sizes by disabling EOP padding.
