UNIC: config function guid to hw in periodic service task

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8GIXF


CVE: NA

-----------------------------------------------------------

In the current version, the unic driver configures the
function guid to the hardware during initialization.
However, no processing is performed after the configuration
fails. As a result, the function guid may not be configured
to the hardware.

This patch adds the process of configuring the function
guid to the periodic task to ensure that the function guid
can be configured to the hardware.
