f2fs: update_sit_entry: Make the judgment condition of f2fs_bug_on more intuitive
Current judgment condition of f2fs_bug_on in function update_sit_entry():
new_vblocks >> (sizeof(unsigned short) << 3) ||
new_vblocks > sbi->blocks_per_seg
which equivalents to:
new_vblocks < 0 || new_vblocks > sbi->blocks_per_seg
The latter is more intuitive.
