usb: otg: twl4030-usb: Fix unbalanced regulator disables at module removal

Function twl4030_usb_remove can cause unbalanced regulator disables in
twl4030_phy_power if the cable is not connected. Regulator enable/disable
calls are in balance only if the twl4030_phy_resume was called prior the
twl4030_usb_remove, that is, the cable was connected.

Fix this by checking the 'asleep' variable in twl4030_usb_remove since that
variable is used to check state in other functions.
