vmlinux.lds.h: Remove a reference to no longer used sections .text..refcount 

Sections .text..refcount were previously used to hold an error path code
for fast refcount overflow protection on x86, see commit 7a46ec0e2f
("locking/refcounts, x86/asm: Implement fast refcount overflow
protection") and commit 564c9cc84e ("locking/refcounts, x86/asm: Use
unique .text section for refcount exceptions").

The code was replaced and removed in commit fb041bb7c0
("locking/refcount: Consolidate implementations of refcount_t") and no
sections .text..refcount are present since then.

Remove then a relic referencing these sections from TEXT_TEXT to avoid
confusing people, like me. This is a non-functional change.
