media: mc-request.c: allow object_bind in QUEUED state

If a request was queued without a control handler object, and
a control handler object is then created and bound to the request
when copying controls on request completion, then a WARN_ON in
mc-request.c is triggered since at that time the request is in
state QUEUED, and not UPDATING.

But this is too strict, and in this case it must also allow
binding objects when in state QUEUED.

This patch was unfortunately lost when the "always copy the controls
on completion" patch was posted, it should have been part of that
commit.

media: media-request: Fix crash if memory allocation fails

What led to this crash was an injected memory allocation failure in
media_request_alloc():

FAULT_INJECTION: forcing a failure.

__se_sys_ioctl+0xf9/0x160
do_syscall_64+0xf3/0x1b0

When that allocation fails, filp->private_data is left uninitialized
which media_request_close() does not expect and crashes.

To avoid this, reorder media_request_alloc() such that
allocating the struct file happens as the last step thus
media_request_close() will no longer get called for a partially created
media request.
