nilfs2: fix dirty page accounting leak causing hang at write
Bruno Prémont and Dunphy, Bill noticed me that NILFS will certainly
hang on ARM-based targets.
I found this was caused by an underflow of dirty pages counter. A
b-tree cache routine was marking page dirty without adjusting page
account information.
This fixes the dirty page accounting leak and resolves the hang on
arm-based targets.
