scsi: megaraid_sas: add correct return type check for ldio hint logic for raid1
Return value check of atomic_dec_if_positive is required as it returns
old value minus one. Without this fix, driver will send small ios to
firmware path and that will be a performance issue.
Not critical, but good to have r1_ldio_hint as default value in sdev
private.
