bnxt_en: Return -EOPNOTSUPP for ETHTOOL_GREGS on VFs.

Browse source

Debug firmware commands are not supported on VFs to read registers.
This patch avoids logging unnecessary access_denied error on VFs
when user calls ETHTOOL_GREGS.

By returning error in get_regs_len() method on the VF, the get_regs()
method will not be called.
