env_nand: fix incorrect size parameter to ALLOC_CACHE_ALIGN_BUFFER
The third parameter to ALLOC_CACHE_ALIGN_BUFFER is not size (as named),
but rather count (number of elements of the type to allocate). The
current code ends up allocating one copy of env_t for each byte in its
size, which quite possibly ends up overflowing RAM.
This fixes a bug in commit 3801a15 "env_nand: align NAND buffers".
