fix(nuttx): bump submodule for IGMP General Query fix

Browse Source

The fix is upstream as f20cf4aac3 but landed after the 12.12.0 tag, so
moving the submodule onto 12.12.0 dropped a fix the previous branch
already carried. Backport it.

Without it the group address in the IGMP header, a uint16_t[2] that decays
to a pointer, is compared against INADDR_ANY, which is always false. A
General Query then falls through to the group-specific branch, a group is
allocated for 0.0.0.0, and joined groups never have their report timers
restarted, so the querier ages out the membership and multicast delivery
to the device stops.

CONFIG_NET_IGMP is enabled on ark/fmu-v6xrt, px4/fmu-v6xrt,
nxp/mr-canhubk3, nxp/mr-tropic and nxp/tropic-community.
