serial: sc16is7xx: remove obsolete loop in sc16is7xx_port_irq()

Browse source

commit ed647256e8 upstream.

Commit 8344498721 ("sc16is7xx: Fix for multi-channel stall") changed
sc16is7xx_port_irq() from looping multiple times when there was still
interrupts to serve. It simply changed the do {} while(1) loop to a
do {} while(0) loop, which makes the loop itself now obsolete.

Clean the code by removing this obsolete do {} while(0) loop.
