igb: use EOPNOTSUPP instead of ENOTSUPP in igb_get_sset_count()

Browse Source 
igb_get_sset_count() returns -ENOTSUPP when a given stringset is not
supported, causing userland programs to get "Unknown error 524".

Since EOPNOTSUPP should be used when error is propagated to userland,
return -EOPNOTSUPP instead of -ENOTSUPP.
