wwan: iosm: use a flexible array rather than allocate short objects 

GCC array-bounds warns that ipc_coredump_get_list() under-allocates
the size of struct iosm_cd_table *cd_table.

This is avoidable - we just need a flexible array. Nothing calls
sizeof() on struct iosm_cd_list or anything that contains it.
