staging: erofs: fix race of initializing xattrs of a inode at the same time
commit 62dc45979f3f8cb0ea67302a93bff686f0c46c5a upstream.
In real scenario, there could be several threads accessing xattrs
of the same xattr-uninitialized inode, and init_inode_xattrs()
almost at the same time.
That's actually an unexpected behavior, this patch closes the race.
