[Pcsclite-muscle] [PATCH 1/1] pcscdaemon: fix "at_exit() write() failed: Bad file descriptor"

[Herve Codina]

In case of receiving a signal to terminate after init has been completed,
at_exit() is called and tries to write to a closed pipe.

This patch simply set pipe to -1 in order to invalidate it after closing.
Pipe value checks are allready present in the code.
