crypto: amlogic - Remove kcalloc without check
[ Upstream commit 3d780c8a9850ad60dee47a8d971ba7888f3d1bd3 ]
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.
Fixes: 48fe583fe541 ("crypto: amlogic - Add crypto accelerator...")
