ALSA: seq: Remove arbitrary prioq insertion limit

ALSA: seq: Remove arbitrary prioq insertion limit

The sequencer priority queue insertion path uses a hardcoded traversal
limit of 10000 entries.  The value is intended to catch a corrupted list,
but it also becomes a real limit for valid queues.

The event pool limit is per client, while a sequencer queue can be shared
by multiple clients.  A queue can therefore legitimately contain more than
10000 events.  In that case, inserting an event that has to be placed past
the arbitrary limit fails with -EINVAL.

Use the queue's own cell count as the traversal bound instead.  This keeps
the protection against inconsistent list accounting or cyclic lists without
rejecting valid large queues.
