[c-nsp] FWSM: secondary not writing to flash

[Ryan Hughes]

Anyone ever run into this error with an FWSM?  3.2(8) code on a sup720 with
12.2(33)SHX2a code.. Essentially the secondary doesn't want to write to disk
when the primary replicates to it.

%Error copying flash:/startup-config (Cannot overwrite image (asdm) file
with ascii text file.)
%Error writing to flash:/startup-config (Source and destination file types
differ)
