[PATCH] proc_fd_getattr(): don't bother with S_ISDIR() check

[Al Viro <viro@zeniv.linux.org.uk>]

[don't really care which tree that goes through; right now it's
in viro/vfs.git #work.misc, but if somebody prefers to grab it
through a different tree, just say so]

that thing is callable only as ->i_op->getattr() instance and only
for directory inodes (/proc/*/fd and /proc/*/task/*/fd)
