linuxcncrsh man page, remove wrong note

Forum user k-1 reported that the man page note conflicts with
observed behavior.
ref: https://forum.linuxcnc.org/forum/24-hal-components/30500-linuxcncrsh-need-suggest-for-chang-open-prog#70984

I can find no usages of the message EMC_TASK_PLAN_CLOSE_TYPE that
was cited as reason for the note (msg is defined but not used).
