RDMA/bnxt_re: use firmware provided max request timeout
Firmware provides max request timeout value as part of hwrm_ver_get
API. Driver gets the timeout from firmware and if that interface is
not available then fall back to hardcoded timeout value.
Also, Add a helper function to check the FW status.
