extcon: max77843: Use correct size for reading the interrupt register
commit c4924e92442d7218bd725e47fa3988c73aae84c9 upstream.
The info->status[] array has 3 elements. We are using size
MAX77843_MUIC_IRQ_NUM (16) instead of MAX77843_MUIC_STATUS_NUM (3) as
intended.
Fixes: 135d9f7d135a ('extcon: max77843: Clear IRQ bits state before request IRQ')
