afs: Declare init_hckernel_mutex()

Browse Source 
The function init_hckernel_mutex() (in rand.c) is flagged due to a
missing prototype when building against a Linux 6.8 kernel (which sets
the -Wmissing-declarations and -Wmissing-prototypes compiler flags as
default). Linux 6.8 commit:
 'Makefile.extrawarn: turn on missing-prototypes globally' (0fcb70851f).

When building against a kernel with CONFIG_WERROR=y, the build fails.

Add a function prototype for init_hckernel_mutex() to afs_osi.h and
remove the prototype from afs_osi.c

There are no functional changes with this commit.
