update DTX fill frame test expectations

Fix an off-by-one in frame number comparison: Ensure that we
won't stop testing until after fn + 104 has been received.

The DTX test case would never pass since the alt statement
was always repeated even if enough frames had been received.
Fix this by moving code which runs before frame fn + 104 is
received into an 'else' cause.

We receive SACCH frames in DTX mode so we must account for them.
Introduce separate counters for SACCH and non-SACCH fill frames
to make test failure diagnosis easier. Note that we cannot expect
a specific amount of SACCH frames during a particular test run
since their amount depends on what the current frame number window
happens to be. We can however add the counters for SACCH and
non-SACCH fill frames and obtain a meaningful result.
