md: replace deprecated strlcpy & remove duplicated line
This commit includes two topics:
1> replace deprecated strlcpy
change strlcpy to strscpy for strlcpy is marked as deprecated in
Documentation/process/deprecated.rst
2> remove duplicated strlcpy line
in md_bitmap_read_sb@md-bitmap.c there are two duplicated strlcpy(), the
history:
- commit cf921cc19cf7 ("Add node recovery callbacks") introduced the first
usage of strlcpy().
- commit b97e92574c0b ("Use separate bitmaps for each nodes in the cluster")
introduced the second strlcpy(). this time, the two strlcpy() are same,
we can remove anyone safely.
- commit d3b178adb3a3 ("md: Skip cluster setup for dm-raid") added dm-raid
special handling. And the "nodes" value is the key of this patch. but
from this patch, strlcpy() which was introduced by b97e92574c0bf
become necessary.
- commit 3c462c880b52 ("md: Increment version for clustered bitmaps") used
clustered major version to only handle in clustered env. this patch
could look a polishment for clustered code logic.
So cf921cc19cf7 became useless after d3b178adb3a3a, we could remove it
safely.
