[PATCH v1 1/1] Bluetooth: MGMT: Use correct address for memcpy()

[Andy Shevchenko]

In function ‘fortify_memcpy_chk’,
    inlined from ‘get_conn_info_complete’ at net/bluetooth/mgmt.c:7281:2:
include/linux/fortify-string.h:592:25: error: call to ‘__read_overflow2_field’ declared with attribute warning: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Werror=attribute-warning]
  592 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

This is due to the wrong member is used for memcpy(). Use correct one.
