wifi: iwlwifi: fix pointer arithmetic in iwl_add_mcc_to_tas_block_list

Browse source

The expression list[*size++] increments the pointer 'size'
rather than the u8 value it points to (operator precedence: ++
binds to the pointer before the dereference). As a result the
block-list entry is written at the correct index but *size is
never incremented, so the caller's count stays at zero and
subsequent calls overwrite slot 0 every time.

Change to list[(*size)++] so that the value pointed to by size
is incremented after use as the array index.
