ALSA: line6: Reject too small max packet sizes

Although the LINE6 driver has a sanity check for the given max packet
sizes, it still has an implicit requirement of the minimal size being
bytes-per-frame; e.g. the impulse test signal assuming the fixed size,
and when a too small size is specified by a malformed USB descriptor,
this may lead to an OOB access.

Change the sanity check conditions to reject too small max packet
sizes for avoiding the scenario above.
