hfs: add error checking for hfs_find_init()
hfs_find_init() may fail with ENOMEM, but there are places, where the
returned value is not checked. The consequences can be very unpleasant,
e.g. kfree uninitialized pointer and inappropriate mutex unlocking.
The patch adds checks for errors in hfs_find_init().
