CHROMIUM: USB: serial: keyspan.c: initialize fw

The fw variable is initialized in request_ihex_firmware in the
non-failure case but the compiler is not smart enough to pick
this up so fixing this way.

Fixes the following warning:
drivers/usb/serial/keyspan.c:1298:18: warning: 'fw' may be used uninitialized in this function [-Wmaybe-uninitialized]

BUG=chromium-os:5542
TEST=compile
