RDMA/bnxt_re: Add SRQ support for Broadcom adapters
Shared receive queue (SRQ) is defined as a pool of
receive buffers shared among multiple QPs which belong
to same protection domain in a given process context.
Use of SRQ reduces the memory foot print of IB applications.
Broadcom adapters support SRQ, adding code-changes to enable
shared receive queue.
