mtd: nand: fix memory leak in ONFI extended parameter page
This fixes a memory leak in the ONFI support code for detecting the
required ECC levels from this commit:
commit 6dcbe0cdd83fb5f77be4f44c9e06c535281c375a
Author: Huang Shijie <b32955@freescale.com>

mtd: get the ECC info from the Extended Parameter Page
In the success case, we never freed the 'ep' buffer.
Also, this fixes an oversight in the same commit where we (harmlessly)
freed the NULL pointer.
