[RFC PATCH 4/7] am437x-vpfe/fimc-capture: always return 0 on close

[Hans Verkuil <hverkuil@xs4all.nl>]

From: Hans Verkuil <hans.verkuil@cisco.com>

When the filehandle is closed always return 0 and ignore the return
code from _vb2_fop_release().

Currently _vb2_fop_release() always returns 0, but this will change in
the next patch where _vb2_fop_release() will return a boolean telling the
caller if this was the last open filehandle that is closed.
