From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

in_interrupt() is ill defined and does not provide what the name
suggests. The usage especially in driver code is deprecated and
a tree wide effort to clean up and consolidate the (ab)usage of
in_interrupt() and related checks is happening.

handle_regs_int() is always invoked as part of URB callback which is either
invoked from hard or soft interrupt context.

Remove the magic assertion.
