ALSA: control: Re-order bounds checking in get_ctl_id_hash()

These two checks are in the reverse order so it might read one element
beyond the end of the array.  First check if the "i" is within bounds
before using it.

Fixes: 6ab55ec0a938 ("ALSA: control: Fix an out-of-bounds bug in get_ctl_id_hash()")
