ubifs: lpt: Fix wrong pnode number range in comment

saschahauer · richardweinberger · commit e1db654d8e32 · 2018-06-07T15:53:15.000+02:00
The comment above pnode_lookup claims the range for the pnode number is
from 0 to main_lebs - 1. This is wrong because every pnode has
informations about UBIFS_LPT_FANOUT LEBs, thus the corrent range is
0 to to (main_lebs - 1) / UBIFS_LPT_FANOUT.
