Log stderr of sdparm to file sdparm.error

There might be output on stderr like:

| root@grml ~ # sdparm --all --long  /dev/sda > /dev/null
| descriptor overflows reply len (12) for AT_LAST.1
| descriptor overflows reply len (12) for CDA_UNIT.1
| descriptor overflows reply len (12) for CDB_UNIT.1
| descriptor overflows reply len (12) for IOA_MODE.1

Ensure to log it to file "sdparm.error".
