esas2r: Use __mem_to_flex() with struct atto_ioctl
As part of the work to perform bounds checking on all memcpy() uses,
replace the open-coded a deserialization of bytes out of memory into a
trailing flexible array by using a flex_array.h helper to perform the
allocation, bounds checking, and copying. This requires adding the
flexible array explicitly.
