qcacmn: Do not use WBM2SW4 as tx completion ring

Browse Source 
Ageout flush does not happen for WBM2SW4 if there
is only one TX completion pending in FIFO and all the
other WBM release rings are not active. This is due to
an issue in HW and this prevents suspend to happen due
to pending tx completions.

Fix is to avoid using WBM2SW4 release ring and instead
reuse WBM2SW0.
