shash_desc is present also in other places in the kernel (there's even a
convenience macro SHASH_DESC_ON_STACK available for defining such stack

several places of the kernel (e.g. kernel/kexec.c and lib/digsig.c)
which have the benefit of not exhibiting the sparse warning.

Since there are no more sparse warnings in the Bluetooth subsystem after

introduced by future patches.
