init.qcom.usb.sh: Remove the diag_extra section

The handling of the persist.sys.usb.config.extra property currently
reads the existing value and attempts to set the correct value based on
ro.baseband. This is fragile as future/unsupported baseband targets would
get the wrong value re-written contrary to what the user originally set.
Further, this does not support ESOC and would have to be added as well.

Simply remove this section altogether, as it would ease future maintenance
effort. As the persist.sys.usb.config.extra property is an undocumented
test feature which is not enabled by end-users, we don't necessarily need
script logic to handle it, and can instead place the burden of setting it
correctly on the developer/tester.

init.qcom.usb.sh: Initialize persist.sys.usb.config.extra property

commit c6a666ce "init.qcom.usb.sh: Remove the diag_extra section"
removed the section that sanitizes the persist.sys.usb.config.extra
property. However, if it is unset, the init.qcom.usb.rc rules will
fail to parse the empty property upon USB composition switch to
RNDIS. Instead, it needs to at least be initialized to 'none' if
not already set.
