crypto: 842 - remove WARN inside printk
Remove the WARN() from the beN_to_cpu macro, which is used as a param to a
pr_debug() call. With a certain kernel config, this printk-in-printk
results in the no_printk() macro trying to recursively call the
no_printk() macro, and since macros can't recursively call themselves
a build error results.
