Hemanth Kumar M D 8e82d7a9bf unfs3: Fix race issue causing a glibc test hang
When running glibc tests under user mode NFS, tst-syslog was causing a hang. The
hang was traced to unfsd exitting with a buffer overflow being detected.

This was traced down to mksocket() where we'd see:

socket path '/media/build/poky/build/build-st-2118464/tmp/work/x86-64-v3-poky-linux/glibc-testsuite/2.42+git/build-x86_64-poky-linux/testroot.root/dev/log' is too long at 141 vs 108

There is a length check in mknod_args() but obj may not be setup at this point by
cat_name() since the functions can be executed out of order according to C.

To avoid this, make the order explict. This means the length is checked and we
avoid the buffer overflow. This will likely cause the glibc test to fail however
it won't hang, which is a win.

[YOCTO #16113]
