bnxt_en: Reduce memory usage when running in kdump kernel.
Skip RDMA context memory allocations, reduce to 1 ring, and disable
TPA when running in the kdump kernel. Without this patch, the driver
fails to initialize with memory allocation errors when running in a
typical kdump kernel.
Fixes: cf6daed098d1 ("bnxt_en: Increase context memory allocations on 57500 chips for RDMA.")
