fs: dlm: lockspace.c: removal of unnecessary check before calling kfree()

kfree() checks its argument. It is therefore unnecessary to do this twice.

This issue was detected using Coccinelle.

I'll drop that too :)

Would you like to add any tags to my update suggestion?

Are you looking for more opportunities around clean-up of such safety checks in Linux source code?
