Victoria Milhoan 8af7b0f809 crypto: caam - Fix incorrect size when DMA unmapping buffer
The CAAM driver uses two data buffers to store data for a hashing operation,
with one buffer defined as active. This change forces switching of the
active buffer when executing a hashing operation to avoid a later DMA unmap
using the length of the opposite buffer.
