crypto: talitos - Fix return type of current_desc_hdr()

Browse Source 
[ Upstream commit 0237616173fd363a54bd272aa3bd376faa1d7caa ]

current_desc_hdr() returns a u32 but in fact this is a __be32,
leading to a lot of sparse warnings.

Change the return type to __be32 and ensure it is handled as
sure by the caller.
