e2fsck: read only parameter incorrectly compared

Don't check for lost+found in read only mode.

[Note: this patch was originally made against 1.41.14 version of
e2fsprogs found as part of the AOSP (Android Open Source Program)
tree.  My Signed-off-by relies on the fact that the original patch
author would have had to have filed a contribution agreement with Open
Handset Alliance before this commit before this commit was allowed
into the AOSP tree. -- tytso]
