[PATCH 1/1] xfs: silent -Wformat-security warning

[Nicolas Iooss <nicolas.iooss_linux@m4x.org>]

When building the XFS driver with clang, the compiler reports a
-Wformat-security warning in xlog_recover_validate_buf_type() because
xfs_warn() is being called with a non-literal string. Even though
variable warnmsg is always initialized as a constant string without any
'%' character, silent the warning by calling xfs_warn with "%s" format
string.
