[PATCH] erofs-utils: lib: capture errors from {mkfs,rebuild}_handle_inode()

[Hongzhen Luo]

Currently, the error code returned by erofs_{mkfs,rebuild}_handle_inode()
in erofs_mkfs_dump_tree() may be ignored. This patch introduces `err1` and
`err2` to capture errors from the {mkfs,rebuild}_handle_inode() functions.
