[BUG] extfs bug

[Adam Byrtek 'alpha']

When I copy file into an archive (tested on urar and uzip extfs) the
file is copied, but when I try to view it, I see:

Cannot view: not a regular file

The problem disappears when I restart mc (I can view the same file
without any problem), so it looks like vfs cache problem.

I tried to examine this issue better, but I lack deeper mc
architecture knowlege.

alpha
