Subject: [PATCH] drmgr: fix remove by index operation

The commit e9f06531356f ("drmgr: introduce NUMA based LMB removal")
introduce a special processing when NUMA is on and the remove by count
operation is done.

Unfortunately, that code is also triggered when doing a remove by index
operation (-s argument) becauses usr_drc_count is set to 1. As a
consequence the index constraint is not respected and any LMB can be
removed.

Add a check agains usr_drc_index which is set when a remove by index
operation is done to ensure the numa removal code is not triggered in that
case.
