Subject: [PATCH] exfat: fix erroneous discard when clear cluster bit

If mounted with discard option, exFAT issues discard command when clear
cluster bit to remove file. But the input parameter of cluster-to-sector
calculation is abnormally adds reserved cluster size which is 2, leading
to discard unrelated sectors included in target+2 cluster.

Fixes: 1e49a94cf707 ("exfat: add bitmap operations")

Could you remove the wrong comments above set/clear/find bitmap functions

Thanks for the review.
