USB: fix coccinelle warnings
drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0, suggest !E
/c/kernel-tests/src/cocci/drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0
Compare pointer-typed values to NULL rather than 0
Semantic patch information:
This makes an effort to choose between !x and x == NULL. !x is used
if it has previously been used with the function used to initialize x.
This relies on type information. More type information can be obtained
using the option -all_includes and the option -I to specify an
include path.
