samples: bluetooth: mesh: fix overflow on nrf52dk/nrf52832

tomi-font · tomi-font · commit 92ce87388447 · 2026-05-26T14:30:56.000+03:00
At revision 3f1c9b9 the builds still had CONFIG_BT_BUF_EVT_DISCARDABLE_SIZE equal to 58, but something made it change to 255 which increases the RAM usage by 4kB and results in overflows on this board target. Explicitly set the value back to 58 to avoid overflows. Signed-off-by: Tomi Fontanilles <tomi.fontanilles@nordicsemi.no>
