bnxt_en: Fix devlink info's stored fw.psid version format.

The running fw.psid version is in decimal format but the stored
fw.psid is in hex format.  This can mislead the user to reset the
NIC to activate the stored version to become the running version.

Fix it to display the stored fw.psid in decimal format.
