wifi: ath11k: fix NULL dereference in ath11k_qmi_m3_load()
commit 3fd2ef2ae2b5c955584a3bee8e83ae7d7a98f782 upstream.
If ab->fw.m3_data points to data, then fw pointer remains null.
Further, if m3_mem is not allocated, then fw is dereferenced to be
passed to ath11k_err function.
Replace fw->size by m3_len.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 7db88b962f06 ("wifi: ath11k: add firmware-2.bin support")
