Horia Geantă 80688afb9c crypto: caam - fix overflow on long hmac keys
When a key longer than block size is supplied, it is copied and then
hashed into the real key.  The memory allocated for the copy needs to
be rounded to DMA cache alignment, as otherwise the hashed key may
corrupt neighbouring memory.

The copying is performed using kmemdup, however this leads to an overflow:
reading more bytes (aligned_len - keylen) from the keylen source buffer.
Fix this by replacing kmemdup with kmalloc, followed by memcpy.

Fixes: 199354d7fb ("crypto: caam - Remove GFP_DMA and add DMA alignment padding")
