Jeremy Kerr c443acab2e [POWERPC] spufs: Fix context destroy vs /spu readdir race
We can currently cause an oops by repeatedly creating and destroying
contexts, while doing getdents() calls on the "/spu" directory.

This is due to the context's top-level dentry remaining hashed while
the context is being destroyed.

Fix this by unhashing the context's dentry with the
dentry->d_inode->i_mutex held. This way, we'll hit the check for
d_unhashed in dentry_readdir, and won't be included in the
list of subdirs for /spu.
