dm crypt: fix get_key_size compiler warning if !CONFIG_KEYS

[ Upstream commit 6fc5150438 ]

Explicitly convert unsigned int in the right of the conditional
expression to int to match the left side operand and the return type,
fixing the following compiler warning:

drivers/md/dm-crypt.c:2593:43: warning: signed and unsigned
type in conditional expression [-Wsign-compare]

Fixes: c538f6ec9f ("dm crypt: add ability to use keys from the kernel key retention service")
