[PATCH] usb: musb: Fix NULL check on struct musb_request field

[Paul Cercueil]

The 'request' variable is a pointer to the 'request' field of the
struct musb_request 'req' pointer. It only worked until now because
the 'request' field is the first one in the musb_request structure, but
as soon as that changes, the check will be invalid.

Fix it preventively by doing the NULL-check on the 'req' pointer
instead.
