/*
* Internal Function: udf_aerospike_delbin
*
* Parameters:
* r - udf_record to be manipulated
* bname - name of the bin to be deleted
*
* Return value:
* 0 on success
* -1 on failure
*
* Description:
* The function deletes the bin with the name
* passed in as parameter. The as_bin_destroy function
* which is called here, only frees the data and
* the bin is marked as not in use. The bin can then be reused later.
*
* Synchronization : object lock acquired by the transaction thread executing UDF.
* Partition reservation takes place just before the transaction starts executing
* ( look for as_partition_reserve_udf in thr_tsvc.c )
*
* Callers:
* udf_aerospike__apply_update_atomic
* In this function, if it fails at the time of update, the record is set
* to rollback all the updates till this point. The case where it fails in
* rollback is not handled.
*
* Side Notes:
* i. write_to_device will be set to true on a successful bin destroy.
* If all the updates from udf_aerospike__apply_update_atomic (including this) are
* successful, the record will be written to disk and reopened so that the rest of
* sets of updates can be applied.
*
* ii. If delete from sindex fails, we do not handle it.
