Staging: wlags49_hs2: Fix wlags49_hs2 driver after build fixes broke it

Fixes the driver after merge into the 2.6.34 kernel. Driver should
be functional again (a fix to make it compile broke the driver).

Patch against 2.6.34 RC7 with patch-v2.6.34-rc7-next-20100513
already applied.

Removed conditional code based on kernel version, this is pointless
now the driver is part of the kernel. Also removed obsolte code
left over from previous patches. Includes also small fixes to compile
clean again.
