  jpeg2000dec: Add more checks when parsing headers

The check cannot be true in FFmpeg, but does no harm.
I will move it in a subsequent commit so it can detect missing SIZ

With some (buggy) drivers, the VIDIOC_G_STD ioctl returns a std_id that cannot
be matched with any of the enumerated v4l2_standard structures (for example
std_id = 0 or std_id = 0xffffff). Do not fail when we reach the end of the
enumeration without a valid match.

Fixes ticket #2370

Note: This commit message has been modified by Giorgio Vazzana, the original
commit message was:

"Fixed regression for mandatory VIDIOC_ENUMSTD support by v4l2"

It's not our responsibility to account for other projects'
terrible hacky usage.

Also, it is no longer needed by XMBC, since 78b71d4.

Previously this would have lead to a memcpy(a,a) which violates the
requirement of non overlapping src and dst.

Since the errors are not fatal, it is less confusing not to show them as
errors but as warnings.

Conflicts:

A failure to reallocate should not free the array as it is used
to probe the codec. And failure to reallocate if the following
probe succeeds isnt a fatal error for probe_codec(). Thus this
is only partially merged to ensure probing still is attempted
with the data available.
