[PATCH] rt2x00: Only strip preamble bit in rt2400pci

[Ivo van Doorn <ivdoorn@gmail.com>]

Only rt2400pci can have the preamble bit set in the PLCP value,
for all other drivers it should not be cleared since that will
conflict with the plcp values for OFDM rates.

John, I have put this patch in the upstream branch of rt2x00.git as well,
so when you merge the rt2x00 2.1.4 pull request into wireless-testing you'll
get this one automatically as well.

Apparently one of the late patches I moved into rt2x00.git tonight broke
connectivity with 54Mb AP's (while the tests run today were with a 11Mb AP,
hence it was unoticed during the 2.1.4 release test cycle).
