David Howells fe276165b0 hypfs: Fix error number left in struct pointer member
[ Upstream commit b54c64f7adeb241423cd46598f458b5486b0375e ]

In hypfs_fill_super(), if hypfs_create_update_file() fails,
sbi->update_file is left holding an error number.  This is passed to
hypfs_kill_super() which doesn't check for this.

Fix this by not setting sbi->update_value until after we've checked for
error.
