USB: dwc3_otg: Use correct delay for sm_work scheduling in A_IDLE 



commit 711b9b11: "USB: dwc3_otg:
Retry if vbus regulator get fail with -EPROBE_DEFER" is required
for scheduling sm_work after one sec in case vbus_regulator get
fails when host cable connected during bootup. This introduced a
bug where sm_work is scheduled for delay much greater than one sec.
Hence fix the issue by using correct delay in case vbus_regulator
get fails during bootup.
