[PATCH] mtd: davinci_nand: Remove unnecessary labels from error path

[Prabhakar Lad]

From: "Lad, Prabhakar" <prabhakar.csengg at gmail.com>

This patch removes the unnecessary labels from
the error path in probe function which did nothing
than just returning error values, Thus simplifying code
path and improved readability.
