Remove redundant lock in SSLSocketImpl.
In the SSLSocketImpl, there is a socket level lock while reading application
data (see readApplicationRecord).
socketLock.lock();
try {
plainText = decode(buffer);
} finally {
socketLock.unlock();
}
If an application data read is in progress, other calling to SSLSocket APIs
(for example getUseClientMode()) could be blocked if socket level locks are
used.
No new regression test. Simple fix, hard to trigger the deadlock.
