cryptfs: Don't hardcode ikey buffer size
We were hardcoding the size of the ikey buffer, but then had logic
which used KEY_LEN_BYTES and IV_LEN_BYTES to offset into the array
and describe the length of its contents.
In anticipation of allowing the keysize to be set via a property,
instead of at compile time, we change this code to make the relation
between the keysize and the buffer size explicit.

Test: Flashed an encrypted sailfish and it booted.
