Zhihao Cheng 7f0b3524a6 ubifs: Correct the total block count by deducting journal reservation 
[ Upstream commit 84a2bee9c4 ]

Since commit e874dcde1c ("ubifs: Reserve one leb for each journal
head while doing budget"), available space is calulated by deducting
reservation for all journal heads. However, the total block count (
which is only used by statfs) is not updated yet, which will cause
the wrong displaying for used space(total - available).
Fix it by deducting reservation for all journal heads from total
block count.

Fixes: e874dcde1c ("ubifs: Reserve one leb for each journal head while doing budget")
