crypto: skcipher - fix weak key check for lskciphers

Browse Source 
When an algorithm of the new "lskcipher" type is exposed through the
"skcipher" API, calls to crypto_skcipher_setkey() don't pass on the
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS flag to the lskcipher.  This causes
self-test failures for ecb(des), as weak keys are not rejected anymore.
Fix this.
