drivers: bluetooth: h4: Fix check for sufficient buffer size
When alloc the evt buffer,such as the adv report, only compare the
remaining data len, should aslo consider the hdr_len, because the
hdr also copy to alloced buffer.if not consider the hdr, then
hdr + remaining data may larger than alloced buffer, because the
alloced buffer is not enough,then will assert when receive the
remaining data.
