crypto: caam - fix RNG deinstantiation error checking
RNG instantiation was previously fixed by commit62743a4145
("crypto: caam - fix RNG init descriptor ret. code checking") while deinstantiation was not addressed. Since the descriptors used are similar, in the sense that they both end with a JUMP HALT command, checking for errors should be similar too, i.e. status code 7000_0000h should be considered successful.
