Subject: [PATCH] block: mark invalidate_partition static
References: bsc#1175995,jsc#SLE-15608
Git-commit: 02d33b6771fcc63c98cb48cad0cd8b8fb033837a
Patch-mainline: v5.8-rc1

invalidate_partition is only used in genhd.c, so mark it static.  Also
drop the return value given that is is always ignored.
