'cmd' is malloced in ath10k_bmi_lz_data_large() and should be freed
before leaving from the error handling cases, otherwise it will cause
memory leak.
Fixes: d58f466a5dee ("ath10k: add large size for BMI download data for SDIO")

Please don't add "net-next" to wireless-driver patches (ath10k, ath11k
etc), because we use different trees. You can add "-next" or
"wireless-driver-next" if you want, but even that is not necessary as I
apply patches to -next by default.
