i40e: Fix firmware version comparison function
Helper i40e_is_fw_ver_eq() compares incorrectly given firmware version
as it returns true when the major version of running firmware is
greater than the given major version that is wrong and results in
failure during getting of DCB configuration where this helper is used.
Fix the check and return true only if the running FW version is exactly
equals to the given version.
Reproducer:
1. Load i40e driver
2. Check dmesg output
[root@host ~]# modprobe i40e
[root@host ~]# dmesg | grep 'i40e.*DCB'
[ 74.750642] i40e 0000:02:00.0: Query for DCB configuration failed, err -EIO aq_err I40E_AQ_RC_EINVAL
[ 74.759770] i40e 0000:02:00.0: DCB init failed -5, disabled
[ 74.966550] i40e 0000:02:00.1: Query for DCB configuration failed, err -EIO aq_err I40E_AQ_RC_EINVAL
[ 74.975683] i40e 0000:02:00.1: DCB init failed -5, disabled
