[PATCH 17/31 v2] build fix: ath_hal_getrtsaggrlimit can be removed here

[Oleksij Rempel]

reason for this part of code:
"AR5416/AR5418 doesn't work with RTS + aggregates longer than 8KiB,
so the driver has to either limit aggregate sizes to 8KiB or less,
or disable RTS on longer aggregates. This was fixed in subsequent chips."
