[PATCH net] ipv4: igmp: Remove redundant comparison in igmp_mcf_get_next()

From: Gavrilov Ilia
Date: Mon Aug 28 2023 - 05:12:23 EST


The 'state->im' value will always be non-zero after
the 'while' statement, so the check can be removed.

Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.
