scsi: hisi_sas: Remove redundant checks for automatic debugfs dump

In commit 63f0733d07ce ("scsi: hisi_sas: Allocate DFX memory during dump
trigger"), the memory allocation time of the DFX is changed from device
initialization to dump occurs, so .debugfs_itct is not a valid address and
do not need to check.

The parameter hisi_sas_debugfs_enable is enough to check whether automatic
debugfs dump is triggered, so remove redunant checks.
