[PATCH AUTOSEL 4.18 016/136] uwb: hwa-rc: fix memory leak at probe

[Sasha Levin]

From: Anton Vasilyev <vasilyev@xxxxxxxxx>

[ Upstream commit 11b71782c1d10d9bccc31825cf84291cd7588a1e ]

hwarc_probe() allocates memory for hwarc, but does not free it
if uwb_rc_add() or hwarc_get_version() fail.

Found by Linux Driver Verification project (linuxtesting.org).
