[PATCH v3 3/9] hw/usb: reorder fields in UASStatus

[Daniele Buono]

The UASStatus data structure has a variable sized field inside of type uas_iu,
that however is not placed at the end of the data structure.

This placement triggers a warning with clang 11, and while not a bug right now,
(the status is never a uas_iu_command, which is the variable-sized case),
it could become one in the future.

../qemu-base/hw/usb/dev-uas.c:157:31: error: field 'status' with variable sized 
type 'uas_iu' not at the end of a struct or class is a GNU extension 
[-Werror,-Wgnu-variable-sized-type-not-at-end]
    uas_iu                    status;
                              ^
1 error generated.

Fix this by moving uas_iu at the end of the struct
