scsi: target: sbitmap: add seq_file forward declaration
The target core runs into a warning in the linux/sbitmap.h
file in some configurations:
In file included from include/target/target_core_base.h:7,
from drivers/target/target_core_fabric_lib.c:41:
include/linux/sbitmap.h:331:46: error: 'struct seq_file' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
void sbitmap_show(struct sbitmap *sb, struct seq_file *m);
^~~~~~~~
In general, headers should not depend on others being included first,
so this fixes it with a forward declaration for that struct name, but
we probably want to merge the patch through the scsi tree to help
bisection.
Fixes: 10e9cbb6b531 ("scsi: target: Convert target drivers to use sbitmap")
