ubifs: Fix wrong dirty space budget for dirty inode 



[ Upstream commit b248eaf049d9cdc5eb76b59399e4d3de233f02ac ]

Each dirty inode should reserve 'c->bi.inode_budget' bytes in space
budget calculation. Currently, space budget for dirty inode reports
more space than what UBIFS actually needs to write.
