mlxsw: pci: Query resources before and after issuing 'CONFIG_PROFILE' command

Currently, as part of mlxsw_pci_init(), resources are queried from firmware
before issuing the 'CONFIG_PROFILE' command.

There are resources whose size depend on the enablement of the unified
bridge model that is performed via 'CONFIG_PROFILE' command. As a
preparation for unified bridge model, add an additional query after issuing
this command. Both queries are required as KVD sizes are read from
firmware and then are configured as part of 'CONFIG_PROFILE' command.
