Linux compat 4.16: blk_queue_flag_{set,clear}
queue_flag_{set,clear}_unlocked are now private interfaces in the Linux kernel (https://github.com/torvalds/linux/commit/8a0ac14). Use blk_queue_flag_{set,clear} interfaces which were introduced as of https://github.com/torvalds/linux/commit/8814ce8. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Giuseppe Di Natale <dinatale2@llnl.gov> Closes #7410
