qcacld-3.0: Change roam synch indication RSSI data type

While parsing the roam synch indication event from the firmware,
the RSSI is copied into a uint8_t variable. But RSSI is negative
value. So change the data type of roam_synch_ind->rssi as signed
int8_t type.
Firmware sends absolute value as RSSI so convert it into a negative
value before assigning to the destination buffer.
