[PATCH] ath11k: fix up some error paths

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

There are two error paths where "ret" wasn't set.  Ideally the compiler
would have warned about these bugs, but we initialized "ret" to zero so
it silenced the warning.  I have removed that.  Also if
ath11k_hal_srng_get_entrysize() fails then we need to free some
resources before returning.

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