vfs: show filesystem name at dump_inode()
Commit 8b17e540969a ("vfs: add initial support for CONFIG_DEBUG_VFS") added
dump_inode(), but dump_inode() currently reports only raw pointer address.
Comment says that adding a proper inode dumping routine is a TODO.
However, syzkaller concurrently tests multiple filesystems, and several
filesystems started calling dump_inode() due to hitting VFS_BUG_ON_INODE()
added by commit af153bb63a33 ("vfs: catch invalid modes in may_open()")
before a proper inode dumping routine is implemented.
Show filesystem name at dump_inode() so that we can find which filesystem
has passed an invalid mode to may_open() from syzkaller's crash reports.
