You could check for
empty(getloclist(0))

" Second approach: always do :lnext and if that fails, try :cnext

nnoremap <A-n> :NextError<CR>
nnoremap <A-p> :PrevError<CR>

com! -bar NextError call s:GoForError("next")
com! -bar PrevError call s:GoForError("previous")

func! s:GoForError(partcmd)
try
try
exec "l". a:partcmd
catch /:E776:/
" No location list
exec "c". a:partcmd
endtry
catch
echohl ErrorMsg
echomsg matchstr(v:exception, ':\zs.*')
echohl None
endtry
endfunc
