wimax/i2400m: fix deadlock: don't do BUS reset under i2400m->init_mutex
Since the addition of the pre/post reset handlers, it became clear
that we cannot do a I2400M-RT-BUS type reset while holding the
init_mutex, as in the case of USB, it will deadlock when trying to
call i2400m_pre_reset().
Thus, the following changes:
- clarify the fact that calling bus_reset() w/ I2400M_RT_BUS while
holding init_mutex is a no-no.
- i2400m_dev_reset_handle() will do a BUS reset to recover a gone
device after unlocking init_mutex.
- in the USB reset implementation, when cold and warm reset fails,
fallback to QUEUING a usb reset, not executing a USB reset, so it
happens from another context and does not deadlock.
