[lvc-project] [PATCH 1/2] wifi: ath10k: do not ignore value returned by ath10k_wmi_peer_set_param()

[Dmitry Antipov]

Do not ignore value returned by 'ath10k_wmi_peer_set_param()' but
rather propagate it as the return value of the 'ath10k_set_key()'.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 9cdd00575029 ("ath10k: fix TDLS peer TX data failure issue on encryped AP")
Fixes: 382e51c139ef ("ath10k: set WMI_PEER_AUTHORIZE after a firmware crash")
