Raw receive functions must not decrypt data

Browse Source 
This patch fixes a small bug found where receive_spill() sometimes
attempted to decrypt spill blocks when doing a raw receive. In
addition, this patch fixes another small issue in arc_buf_fill()'s
error handling where a decryption failure (which could be caused by
the first bug) would attempt to set the arc header's IO_ERROR flag
without holding the header's lock.
