hippi: Fix a Fix a possible sleep-in-atomic bug in rr_close
The driver may sleep under a spinlock.
The function call path is:
rr_close (acquire the spinlock)
free_irq --> may sleep
To fix it, free_irq is moved to the place without holding the spinlock.
This bug is found by my static analysis tool(DSAC) and checked by my code review.
