spfc: Fix compile errors when O=xxx is specified

Ramaxel inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4DBD7


CVE: NA

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

Fix two compile errors:
1. Compile failed when O=xxx is specified;
2. Compile conflicted when spfc and spnic are compiled in parallel
by -j option because they share some .c files.

make O=tmp -j200  > build.log
