[PATCH 1/2] erofs-utils: allocate `struct erofs_inode` with zeroed memory

[Gao Xiang]

The kernel implementation has the same constraint, so the code can
be shared.

Fixes: 9fd2a2250fa9 ("erofs-utils: fuse: switch to FUSE 2/3 lowlevel APIs")
Fixes: f44043561491 ("erofs-utils: introduce fsck.erofs")
