dm crypt: avoid truncating the logical block size

Browse Source 
queue_limits::logical_block_size got changed from unsigned short to
unsigned int, but it was forgotten to update crypt_io_hints() to use the
new type.  Fix it.

Fixes: ad6bf88a6c ("block: fix an integer overflow in logical block size")
