Subject: [PATCH][V2][next] accel/qaic: remove redundant pointer pexec

Pointer pexec is being assigned a value however it is never read. The
assignment is redundant and can be removed. Replace sizeof(*pexec)
with sizeof the type and remove the declaration of pointer pexec.

Signed-off-by: Colin Ian King <colin.i.king@...il.com>
---

V2: completely remove the declaration of pexec and replace sizeof(*pexec)
with size of the type.
