scsi: scsi_debug: Define grammar to remove added error injection

Browse source

The grammar to remove error injection is a line with fixed 3 columns
separated by spaces.

First column is fixed to "-". It tells this is a removal operation.  Second
column is the error code to match.  Third column is the scsi command to
match.

For example the following command would remove timeout injection of inquiry
command:

    echo "- 0 0x12" > /sys/kernel/debug/scsi_debug/0:0:0:1/error
