Subject: [PATCH] ath10k: Fix the size used in a 'dma_free_coherent()' call in an error handling path

Update the size used in 'dma_free_coherent()' in order to match the one
used in the corresponding 'dma_alloc_coherent()'.

Fixes: 1863008369ae ("ath10k: fix shadow register implementation for WCN3990")
Signed-off-by: Christophe JAILLET <christophe.jaillet@...adoo.fr>

This patch looks obvious to me, but commit 1863008369ae looks also simple.
So it is surprising that such a "typo" slipped in.
