[MTD] m25p80: fix detection of SPI parts 

Commit d0e8c47c58 ("m25p80.c extended jedec
support") added support for extended ids but in the process managed to
break detection of all flashes.

The ext jedec id check was inserted into an if statement that lacked
braces, and it did not add the required braces.  As such, the detection
routine always returns the first entry in the SPI flash list.
