tape-admin: rework ltfs reformat and wipe

Browse Source 
* be verbose, if requested
* handle return codes for function call
* to re-format an already partitioned tape, its need to be wiped first
* just simply removing data from tape does not free the occupied space
  thus, we need to wipe it and format again to get full capacity of
  the tape
