net/bnxt: fix ring alignment for Thor-based adapters

Browse Source 
When using transmit/receive queue sizes smaller than 256, alignment
requirements are not being met for Thor-based adapters. Fix by
forcing memory addresses used for transmit/receive/aggregation ring
allocations to be on 4K boundaries.
