For incompleted block allocations or frees, the inode block count usage
must be recalculated. The blk_check pass of suj checker explicitely marks
inodes which owned such blocks as needing block count adjustment. But
ino_adjblks() is only called by cg_trunc pass, which is performed before
blk_check. As result, the block use count for such inodes is left wrong.
This causes full fsck run after journaled run to still find inconsistencies
like 'INCORRECT BLOCK COUNT I=14557 (328 should be 0)' in phase 1.
Fix this issue by running additional adj_blk pass after blk_check, which
updates the field.

the chip select control away from the SPI peripheral and managing it
