[PATCH v3 1/2] erofs-utils: get rid of `end' argument from erofs_mapbh()

[Gao Xiang]

From: Hu Weiwen <sehuww at mail.scut.edu.cn>

`end` arguement is completely broken now. Also, it could
be readded later if needed.

Hi Weiwen,
Sorry for late update. I've cleaned up the patchset (mainly [PATCH 2/2],
could you kindly recheck it on your side if it works, and help me update
the commit message of [PATCH 2/2] as well?

Thanks,
Gao Xiang
