fsck.ubifs: Read master node & init lpt
This is the 1/18 step of fsck. Read and check master node, init lpt.
There could be following errors:
1. corrupted scanning data in master area or invalid master node:
danger mode with rebuild_fs and normal mode with 'yes' answer will
turn to rebuild filesystem, other modes will exit.
2. incorrect space statistics in master node: Set %FR_LPT_INCORRECT for
for lpt status. Ignore the error.
3. corrupted lpt: Set %FR_LPT_CORRUPTED for lpt status. Ignore the error.
