When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to make
sure they can be included from user-space.

Currently, scsi_bsg_fc.h, scsi_netlink.h, and scsi_netlink_fc.h are
excluded from the test coverage. To make them join the compile-test, we
need to fix the build errors attached below.

For a case like this, we decided to use __u{8,16,32,64} variable types in
this discussion:
