exfat: remove the assignment of 0 to bool variable

JasonYanHw · namjaejeon · commit cdc06129a6ce · 2020-06-09T16:48:53.000+09:00
There is no need to init 'sync' in exfat_set_vol_flags().
This also fixes the following coccicheck warning:

fs/exfat/super.c:104:6-10: WARNING: Assignment of 0/1 to bool variable
