bts chan_load: ignore unusable BTS
For unconnected BTS, the channel load would report a "bogus channel load
sample" every second (on RLL debug). Instead, skip unusable BTS.
This follows up on commit 6cee893a0f2c4e53155a2631aff12a5f615b973d /
I57e38f6d6ba3b23cc6e1f9520b90261dbb1f1cec
'Make "waiting indicator" of IMMEDIATE ASSIGN REJECT dynamic.'
