[PATCH] vgaarb: use valid dev pointer in vgaarb_info()

[Arnd Bergmann <arnd@arndb.de>]

We now pass the device to the debug messages, but on non-x86,
this is an invalid pointer in vga_arb_device_init:

drivers/gpu/vga/vgaarb.c: In function 'vga_arb_device_init':
drivers/gpu/vga/vgaarb.c:1467:4: error: 'dev' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This moves the initialization of the dev pointer outside of the
architecture #ifdef.

Fixes: a75d68f62106 ("vgaarb: Use dev_printk() when possible")
