[PATCH] block: fix boolconv.cocci warnings

[kernel test robot]

From: kernel test robot <lkp@xxxxxxxxx>

block/blk-mq-sched.c:404:39-44: WARNING: conversion to bool not needed here

 Remove unneeded conversion to bool

Semantic patch information:
 Relational and logical operators evaluate to bool,
 explicit conversion is overly verbose and unneeded.
