Remove call to ipcperm() in shmget_existing(). The flags argument is
ignored on other systems I investigated when accessing an existing
memory segment rather than creating a new one. This call to ipcperm()
is the only one to pass in a complete mode flag to the permission
checks rather than a simple access request mask, and caused problems
for the revised ipcperm() based on the priv(9) interface, which can
now be restored.
