qcacmn: Fix ce ring timeout interrupt hw work arround

Interrupt was constantly firing because the low_threshold was
improperly configured.  The low threshold needs to be 1 less than
the number of buffers posted when the CE is fully posted.  The
srng backed CE's are setup with nentries - 2 buffers as the fully
posted amount, therefore the threshold needs to be nentries - 3.

Also fixes a bug where a reused variable is not cleared.  This
bug could result in the threshold being set to a garbages value.
