[PATCH ath-next] wifi: ath11k: fix leak in ath11k_service_ready_ext_event()

[Jeff Johnson]

Currently, during ath11k_service_ready_ext_event() processing,
svc_rdy_ext.mac_phy_caps can be allocated during TLV parsing. This is a
temporary allocation that is freed on the success path, but not on the
error path. If parsing succeeds far enough to allocate mac_phy_caps and
then fails on a later TLV, the allocation leaks. So free the allocation
on the error path.

Compile tested only.
