Subject: [PATCH] m25p80: fix detection of SPI parts

Commit d0e8c47c58575b9131e786edb488fd029eba443e 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.
