usrp1: fix transmit side tuning bug 

Transmit tuning was primarily setup for side A only. Some boards
- WBX - would still tune with improper channel arguments, though
receiver performance was disrupted.

Previous testing was primarily with single board on side A only
or dual configuration with side A transmit, so this bug largely
went undetected. Patch tested with RFX and WBX daughterboards
in single and dual configurations sides A and B.
