[PATCH] vfs: fix documentation of touch_atime()

[Luis de Bethencourt]

The documentation of touch_atime() doesn't match the location of the
definition and list of parameters anymore. Updating it.

Fixes: e8d2e3f31127 ("vfs: update ovl inode before relatime check")

Hi,

This patch is based on Miklos' overlayfs-next branch [0]. When building the
docs with the latest changes in that branch you get the following warning:

.//fs/inode.c:1637: warning: No description found for parameter 'rcu'

Problem is that the documentation generator takes the parameter list of
__atime_needs_update for the description of touch_atime() due to the comments
being just above __atime_needs_update().
Moving down the comments to match the location of touch_atime and removing
the explanation of @inode since that parameter isn't there anymore.

Originally the comments were just above atime_needs_update(), should I keep
them above this function instead? Not sure since the comments say touch_atime.

Thanks,
Luis
