[PATCH net-next] [v2] misdn: avoid -Wempty-body warning

From: Arnd Bergmann <arnd@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 */

As the check has no effect, just remove it.

Suggested-by: Leon Romanovsky <leon@kernel.org>

v2: remove the line instead of adding {}
