once: fix section mismatch on clang builds
On older kernels (5.4 and older), building the kernel with clang can cause the section name to end up with "" in them, which can cause lots of runtime issues as that is not normally a valid portion of the string. This was fixed up in newer kernels with commit 33def849 ("treewide: Convert macro and uses of __section(foo) to __section("foo")") but that's too heavy-handed for older kernels. So for now, fix up the problem that commit 62c07983 ("once: add DO_ONCE_SLOW() for sleepable contexts") caused by being backported by removing the "" characters from the section definition.
