Update HackRf.cpp

Browse source 
gainLna and gainVga not populated so insert static values for now. this needs fixing (I presume in blah2.cpp?)

fixed the device check, previously it only triggered if 1 device was connected, but not 0 devices.

other fixes for using pointers instead of deferenced pointers, etc.
