ipcpd: Don't read commands under lock
The commands were read under a mutex. Since the cmd struct was just malloc'd, this is not needed. Also fixes closing the socket if the malloc fails. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
