Hyeongseok Kim 11e3ff7e16 exfat: fix erroneous discard when clear cluster bit ...

commit 77edfc6e51055b61cae2f54c8e6c3bb7c762e4fe upstream.

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 added by reserved cluster size which is 2,
leading to discard unrelated sectors included in target+2 cluster.
With fixing this, remove the wrong comments in set/clear/find bitmap
functions.
