[patch] fix K&R int promotion warnings in sys/compat/ndis/subr_usbd.c

Hi,

Here is a patch to fix the K&R function declaration to match the ANSI
prototypes, done so by ANSIfying the rest of the K&R function
declarations in the file.

http://lev.vlakno.cz/~pwo/warn-fix/ndis-subr_usbd.diff

Sample warning:
/usr/src/sys/modules/ndis/../../compat/ndis/subr_usbd.c:598:13:
warning: promoted type 'int' of K&R function parameter is not
compatible with the parameter type 'uint8_t' (aka 'unsigned char')
declared in a previous prototype
        uint8_t                         ifidx;
                                        ^
/usr/src/sys/modules/ndis/../../compat/ndis/subr_usbd.c:120:59: note:
previous declaration is here
static usb_error_t       usbd_setup_endpoint_one(irp *, uint8_t,
                                                               ^
