qcacmn: Possible information leak due to uninitialized data

Browse source 
In qdf_trace_hex_dump() API, linebuf array is not initialized where
it is used to print in the form of string in qdf_trace_msg() API,
this may cause information leak.

To address this issue, initialize the linebuf array to zero.
