Subject: ixgbe: fix the FWSM.PT check in ixgbe_mng_present()
Patch-mainline: v4.15-rc1
Git-commit: c3aec05dfe2cb1bc1fdf3593da82bc987211338a
References: bsc#1101674 FATE#325150 FATE#325151
Bits other than FWSM.PT can be set in IXGBE_SWFW_MODE_MASK making the
previous check invalid.
Change the check for MNG present to be only based on FWSM.PT bit.
