mtd m25p80: regression fix for chip detection

From: David Brownell <[email protected]>

The "m25p80.c extended jedec support" patch introduced a regression whereby every chip ended up matching the first entry in the list of chips, since it parenthesized a test incorrectly.

This bug could cause MTD filesystem corruption, and all sorts crazy stuff since all chips would appear to be small (128KB) Atmel chips instead of what they really were.
