usb: core: introduce a new usb_get_std_status() helper

This new helper is a simple wrapper around usb_get_status(). This
patch is in preparation to adding support for fetching PTM_STATUS
types. No functional changes.

type selector (standard or ptm).

usb-storage: make use of srb local variable

Commit 8b52291a0743 ("usb-storage: fix deadlock involving host lock
and scsi_done") added a local variable to usb_stor_control_thread() in
the usb-storage driver.  This local variable holds the value of
us->srb, for use after the host lock has been released.

But as long as we have the value in a local variable, we may as well
use it instead of dereferencing the us pointer all over the place.
This patch makes no functional change; it just makes the code a little
shorter and a little neater.
