bsc: Fix "show lchan" for partially provided information

show lchan should be capable of showing all allocated lchans,
all of a given bts, a given trx, a given ts. This feature was
broken when I added the ability to show a more simple summary.

Restore the initial behavior by splitting out the for loops
for the bts/trx/ts and check if we have parsed all parameters
and then call and return the subroutine.
