rate_ctr_group_alloc with identical index doesn't return error
As seen by the bug fixed in Change-Id I1b56f8d7b47597ed263e6808074483edca0895de of osmo-bts.git, (https://gerrit.osmocom.org/#/c/5344) the rate_ctr_group_alloc() function appears to accept allocation of the same counter group for identical index, which is of course an error.
Let's make sure we return an error, and also make sure that all known callers actually deal with the error somehow (e.g. if the BTS counters couldn't be allocated, the entire BTS allocation should fail).

Fix for the library is available in gerrit 5418. We should also make sure that all the callers properly check and handle allocation error (which they should because there're other error paths in allocation function as well).
