Given that there is no point in invoking an accelerated cipher for doing 56-bit symmetric encryption on a single 8-byte block of input, the flexibility of the crypto cipher API does not add much value here, and so we're much better off using a library call into the generic C implementation.

This means that going through all the trouble of using scatterlists etc buys us very little, and we're better off just invoking the arc4 library directly. This also reverts commit 5f4b55699aaf ("CIFS: Fix BUG() in calc_seckey()"), since it is no longer necessary to allocate sec_key on the heap.
