Daniel Rosenberg 24cd460313 ANDROID: sdcardfs: Protect set_top 
If the top is changed while we're attempting to use it, it's
possible that the reference will be put while we are in the
process of grabbing a reference.

Now we grab a spinlock to protect grabbing our reference count.

Additionally, we now set the inode_info's top value to point to
it's own data when initializing, which makes tracking changes
easier.
