commit e514cc0a492a3f39ef71b31590a7ef67537ee04b upstream.
The props->ap[] array is defined like this:
struct alg_props ap[NX_MAX_FC][NX_MAX_MODE][3];
So we can see that if msc->fc and msc->mode are == to NX_MAX_FC or
NX_MAX_MODE then we're off by one.
Fixes: ae0222b728 ('powerpc/crypto: nx driver code supporting nx encryption')
