crypto: amlogic - Remove kcalloc without check

[ Upstream commit 3d780c8a98 ]

There is no real point in allocating dedicated memory for the irqs array.
MAXFLOW is only 2, so it is easier to allocated the needed space
directly within the 'meson_dev' structure.

This saves some memory allocation and avoids an indirection when using the
irqs array.
