top: fix additional SEGVs if no tasks were displayable

Browse Source 
This patch is an outgrowth of that commit shown below.

Many additional potential segmentation faults might be
encountered if interactive commands are opened up to a
user when a '-p' switch has a single non-existent pid.

[ always the 'k', 'L', 'r', 'Y' keys & maybe 'v' too ]

So, this patch will restrict such a loser (oops, user)
to a reduced subset of normal commands until he/she/it
quits then restarts top with something to be displayed
or issues the '=' command overriding that '-p' switch.
