Huang Jianan a60cb39186 erofs: avoid using generic_block_bmap 
[ Upstream commit d8b3df8b1048405e73558b88cba2adf29490d468 ]

Surprisingly, `block' in sector_t indicates the number of
i_blkbits-sized blocks rather than sectors for bmap.

In addition, considering buffer_head limits mapped size to 32-bits,
should avoid using generic_block_bmap.
