f2fs: fix to clear unusable_cap for checkpoint=enable

Browse Source 
mount -t f2fs -o checkpoint=disable:10% /dev/vdb /mnt/f2fs/
mount -t f2fs -o remount,checkpoint=enable /dev/vdb /mnt/f2fs/

kernel log:
F2FS-fs (vdb): Adjust unusable cap for checkpoint=disable = 204440 / 10%

If we has assigned checkpoint=enable mount option, unusable_cap{,_perc}
parameters of checkpoint=disable should be reset, then calculation and
log print could be avoid in adjust_unusable_cap_perc().
