Vbus is switched off (after a_wait_bcon) whenever a device
is disconnected from musb host even when musb is configured
only as host.Earlier we use to switch on the power using
[echo "F" >/proc/driver/musb_hdrc] but now this proc entry is
deleted thus musb doesn't work after device disconnect.
This patch puts is_otg_enabled() check before scheduling
a switch-off timer in disconnect path.
