qcacmn: Check mbox_index as index and check pointer

hif_dev_map_pipe_to_mail_box may return 255 and assign to mbox_index,
which will cause buffer overflow. Another issue is missing NULL check
after allocate memory in function hif_dev_send_buffer.

Fix it by checking NULL/invalid return pointer/index value.
