erofs: harden h_shared_count in erofs_init_inode_xattrs()
`u8 h_shared_count` indicates the shared xattr count of an inode. It is
read from the on-disk xattr ibody header, which should be corrupted if
the size of the shared xattr array exceeds the space available in
`xattr_isize`.
It does not cause harmful consequence (e.g. crashes), since the image is
already considered corrupted, it indeed results in the silent processing
of garbage metadata.
Let's harden it to report -EFSCORRUPTED earlier.
