[PATCH] mtd: eLBC NAND: remove bogus ECC read-back

["Matthew L. Creech" <mlcreech@gmail.com>]

From: Mike Hench <mhench@elutions.com>

The eLBC NAND driver currently follows up each program/write operation with a
read-back of the page, in order to [ostensibly] fill in ECC data for the
caller. However, the page address used for this read is always -1, so the read
will never work correctly.  Remove this useless (and potentially problematic)
block of code.
