be2net: fix port-res desc query of GET_PROFILE_CONFIG FW cmd

Commit 72ef3a88fa ("be2net: set pci_func_num while issuing
GET_PROFILE_CONFIG cmd") passed a specific pf_num while issuing a
GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when
pf_num is zero. But, when pf_num is set to a non-zero value, FW does not
return the Port resource descriptor.
This patch fixes this by setting pf_num to 0 while issuing the query cmd
and adds code to pick the correct NIC resource descriptor from the list of
descriptors returned by FW.

Fixes: 72ef3a88fa ("be2net: set pci_func_num while issuing
		     GET_PROFILE_CONFIG cmd")
