add--interactive: fix missing file prompt for patch mode with "-i"

Browse source 
When invoked as "git add -i", each menu interactive menu
option prompts the user to select a list of files. This
includes the "patch" option, which gets the list before
starting the hunk-selection loop.

As "git add -p", it behaves differently, and jumps straight
to the hunk selection loop.

Since 0539d5e6d (i18n: add--interactive: mark patch prompt
for translation, 2016-12-14), the "add -i" case mistakenly
jumps to straight to the hunk-selection loop. Prior to that
commit the distinction between the two cases was managed by
the $patch_mode variable. That commit used $patch_mode for
something else, and moved the old meaning to the "$cmd"
variable.  But it forgot to update the $patch_mode check
inside patch_update_cmd() which controls the file-list
behavior.

The simplest fix would be to change that line to check $cmd.
But while we're here, let's use a less obscure name for this
flag: $patch_mode_only, a boolean which tells whether we are
in full-interactive mode or only in patch-mode.
