Since r5021 [1], first released in DAHDI-Linux 2.2.0, it's been impossible for
user space to change the rxbufpolicy. This hasn't caused any problems and it's
safe to remove a few more of the vestiges of the rxbufpolicy from the driver.
This streamlines the code path in a few places and saves 8 bytes from the size
of struct dahdi_chan.
The user visible parts are maintained and will indicate
DAHDI_POLICY_IMMEDIATE, like it has since 2.2.0.
