wifi: ath11k: fix NULL dereference in ath11k_qmi_m3_load()

Browse source

commit 3fd2ef2ae2 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.
