Subject: [PATCH] ubi: fix swapped arguments to call to ubi_alloc_aeb

From: Colin Ian King <colin.king@...onical.com>

Static analysis by CoverityScan detected the ec and pnum
arguments are in the wrong order on a call to ubi_alloc_aeb.
Swap the order to fix this.

Fixes: 91f4285fe389a27 ("UBI: provide helpers to allocate and free aeb elements")
