[OE-core] [PATCH V2] mdadm: fix systemd service start up failure

[changqing.li at windriver.com]

From: Changqing Li <changqing.li at windriver.com>

1. mdadm: No mail address or alert command - not monitoring

fixed by use option -y to cause all events to be reported
through 'syslog'.

2. cannot create pid file: No such file or directory

fix by create dir before starting.
