[PATCH 5.10 262/717] ath11k: Fix an error handling path

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit e7bcc145bcd035e56da7b97b033c463b32a5ff80 ]

If 'kzalloc' fails, we must return an error code.

While at it, remove a useless initialization of 'err' which could hide the
issue.

Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
