s390/dasd: remove dasd_stats_generic_show()

Browse Source 
Patch series "s390: A couple of fixes for -Wmissing-prototypes".

This series resolves a couple of -Wmissing-prototypes that I see in my
builds of -next, even though the issues appear to be latent.  This
addresses issues which will be exposed by the later patch
"Makefile.extrawarn: turn on missing-prototypes globally".


This patch (of 2):

With CONFIG_DASD_PROFILE=n, there is a warning that
dasd_stats_generic_show() is missing a prototype:

  drivers/s390/block/dasd.c:1109:5: warning: no previous prototype for 'dasd_stats_generic_show' [-Wmissing-prototypes]
   1109 | int dasd_stats_generic_show(struct seq_file *m, void *v)
        |     ^~~~~~~~~~~~~~~~~~~~~~~

This function has been unused since its introduction in commit
4fa52aa7a8 ("[S390] dasd: add enhanced DASD statistics interface"),
remove it to clear up the warning.
