Subject: usrp1: apply conditional disables/enables to rx and tx
Scapped the old gnuradio code for information about VRQ_FPGA_SET_XX_ENABLE.
It turns out that we should disabled + restore state when changing muxes or rates.
The USRP seems to stream properly when receiving single and dual channel.
Prior to this commit, tx was accicentally always disabled from a few commits ago.
