scsi: target: tcmu: fix error resetting qfull_time_out to default
Problem:
$ cat /sys/kernel/config/target/core/user_0/block/attrib/qfull_time_out
-1
$ echo "-1" > /sys/kernel/config/target/core/user_0/block/attrib/qfull_time_out
-bash: echo: write error: Invalid argument
Fix:
This patch will help reset qfull_time_out to its default
i.e. qfull_time_out=-1.
