block: remove test of incorrect io priority level

Ever since commit eca2040972b4("scsi: block: ioprio: Clean up interface definition"), the macro IOPRIO_PRIO_LEVEL() will mask the level value to something between 0 and 7 so necessarily, level will always be lower than IOPRIO_NR_LEVELS(8).

Remove this obsolete check.
