wimax/i2400m: Correct the error path handlers order in i2400m_post_reset()

When bus_setup fails in i2400m_post_reset(), it falls to the error path handler
"error_bus_setup:" which includes unlock the mutext. However, we didn't ever
try to the obtain the lock when running bus_setup.

The patch is to fix the misplaced error path handler "error_bus_setup:".
