David Howells 97826c821e KEYS: Fix error handling in big_key instantiation
In the big_key_instantiate() function we return 0 if kernel_write() returns us
an error rather than returning an error.  This can potentially lead to
dentry_open() giving a BUG when called from big_key_read() with an unset
tmpfile path.

	kernel BUG at fs/open.c:798!
