qcacmn: Modify ret variable check in hif_pm_runtime_get
Runtime put should be done in hif_pm_runtime_get when
return value of __hif_pm_runtime_get is negative. In
the issue scenario, the ret value will be set to 0 when
the return value of __hif_pm_runtime_get is positive.
The store operation for ret variable somehow did not take
effect and the if check for non-zero ret value to do
runtime put did go through. The return value to
dp_tx_hw_enqueue from hif_pm_runtime_get is the updated
ret value of 0. This will result in double runtime put
for a single runtime get.
Fix is to modify the ret variable check to negative
instead of non-zero to ensure runtime put happens
correctly.
