GTI: fw-util: fix the exception when the kv file swb_nic_present is m…

Summary:
…issing

# Description
The kv file "swb_nic_present" was writed when swb bic is ready. Considering the manufacturing w/o swb tray, we should init the kv file to avoid the exception.

X-link: facebookexternal/openbmc.quanta#4377

Test Plan:
Build and test pass on GTI system

// Remove the kv file and check fw-util is work
root@bmc-oob:~# rm /tmp/cache_store/swb_nic_present
