RFR[T]: 8242027: Clean up LinkResolver::check_klass_accessability

[Claes Redestad]

Hi,

all callers of check_klass_accessability now pass true, so this merges
the two variants of check_klass_accessability into one. Also fixes the
typo. :-)

Bug:    https://bugs.openjdk.java.net/browse/JDK-8242027

Testing: tier1

Thanks!
