crypto: caamctrl: fix array out of bound access
desc_len(desc) returns a result masked by a seven bits mask representing
a descriptor length. The maximum length is 64 u32 words but masking
allows for larger but incorrect values.
This fix adds a bound check to the index of deco.descbuf array
(which is smaller than the maximum of 64 words), to avoid invalid
memory accesses.
