[PATCH] USB: remove redundant assignment to temp

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variable temp is being set at the end of each loop iteration
but this value is never read, it is either being updated in just
the case 1 block or at the end of the loop.  Thus the assignment
is redundant and can be removed.  Cleans up clang warning:

drivers/usb/host/ehci-dbg.c:840:4: warning: Value stored to 'temp'
is never read
