    [MTD] m25p80: fix detection of SPI parts
    
    Commit d0e8c47c58575b9131e786edb488fd029eba443e ("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.
