[FT-2900/FT-1900] Add msg for attempt to upload to locked radio  Fixes #3055
A FT-2900/FT-1900 may be "locked" preventing configuration changes.  An
upload will fail if this is the case.  This patch adds some text to the
upload dialog box to help the user avoid attempting to upload to a
"locked" radio.  It also adds some text to the error message to suggest
the user check to make sure his radio is not locked.
