fs/compat_ioctl.c: suppress two warnings

Browse Source 
fs/compat_ioctl.c: In function 'do_ioctl_trans':
fs/compat_ioctl.c:534: warning: 'karg' may be used uninitialized in this function
fs/compat_ioctl.c:533: warning: 'kcmd' may be used uninitialized in this function
fs/compat_ioctl.c:656: warning: 'ret' may be used uninitialized in this function

Reduces text size by 44 bytes.

If someone calls one of these functions with an unexpected argument, the
code's buggy as-is.
