loop: print lo_encrypt_key_size field of struct loop_info as unsigned

Browse Source 
It is converted to an unsigned value in kernel (see loop_info64_from_old
in drivers/block/loop.c), so let's print it that way despite its type.

* loop.c (decode_loop_info): Print lo_encrypt_key_size as an uint32_t
value.
