crypto: caam - fix RNG deinstantiation error checking
commit 40c98cb57cdbc377456116ad4582c89e329721b0 upstream.
RNG instantiation was previously fixed by
commit 62743a4145bb9 ("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.
Fixes: 1005bccd7a4a6 ("crypto: caam - enable instantiation of all RNG4 state handles")
