nsslapd-errorlog-level of 65536 caused directory server to crash and it was unable to restart.

Issue

• When setting the nsslapd-errorlog-level to 65536 on a running dirsrv instance in an IPA environment. Directory server crashed and was unable to restart.
• Doing the following on a running dirsrv instance in IPA 3.0 cause directory server to crash and was unable to start. We eventually changed it to 8192 for debugging purposes. See parent ticket.
