[PATCH net-next 1/5] misdn: avoid -Wempty-body warning

[Arnd Bergmann]

From: Arnd Bergmann <a...@arndb.de>

gcc warns about a pointless condition:

drivers/isdn/hardware/mISDN/hfcmulti.c: In function 'hfcmulti_interrupt':
drivers/isdn/hardware/mISDN/hfcmulti.c:2752:17: error: suggest braces around 
empty body in an 'if' statement [-Werror=empty-body]
 2752 |                 ; /* external IRQ */

Change this as suggested by gcc, which also fits the style of the
other conditions in this function.
