[PATCH] drivers: mpt3sas: mpt3sas_debugfs: return value check of `mpt3sas_debugfs_root`

[Jing Xu]

Smatch complains that:
mpt3sas_init_debugfs() warn: 'mpt3sas_debugfs_root' is an error 
pointer or valid

There is no need to check the return value of the debugfs_create_dir() 
function, just delete the dead code.

Fixes: 2b01b293f359 ("scsi: mpt3sas: Capture IOC data for debugging purposes")
