Fix a OOB bug in bta_hh_co_get_rpt_rsp

Fix to the regression reported in b/264708304 and b/266585826 added:
The root cause of the regression, the sensor HAL layer expects the HID feature
reports to contain 40 bytes, even less bytes are contained in the data
field.

This updated fix restores the length of data fields with the len arg.
