Currently ath11k_tm_cmd_get_version() uses local variable ret.
optimize ath11k_tm_cmd_get_version() to avoid local variable use.

Tested-on : IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

When optimising something it's always good to provide numbers to show
the improvement. But I can't see how this really improves anything so I
dropped this patch 2.
