lchan_select: fix 'chan_alloc_reverse' may be used uninitialized

GCC 12.1.0 emits -Wmaybe-uninitialized when building with '-O2'.

In function 'populate_ts_list', inlined from 'lchan_avail_by_type' at src/osmo-bsc/lchan_select.c:356:2: src/osmo-bsc/lchan_select.c:248:12: warning: 'chan_alloc_reverse' may be used uninitialized [-Wmaybe-uninitialized] 248 | if (chan_alloc_reverse) { | ^ src/osmo-bsc/lchan_select.c: In function 'lchan_avail_by_type': src/osmo-bsc/lchan_select.c:326:14: note: 'chan_alloc_reverse' was declared here 326 | bool chan_alloc_reverse; | ^~~~~~~~~~~~~~~~~~

This could only happen if in 'enum lchan_select_reason' we had items that are not handled in lchan_avail_by_type(), but this is not the case. Make GCC happy by initializing chan_alloc_reverse to false.
