qcacld-3.0: Fix Use-After-Free in ol_txrx_pdev_detach

The use TAILQ_FOREACH for freeing the fw_stats list during
pdev detach causes a use-after-free condition, which can lead
to unexpected behavior during the driver load or unload.

Fix the possible Use-after-free condition in pdev detach, by
using TAILQ_FOREACH_SAFE instead of TAILQ_FOREACH for freeing
the fw_stats list.
