efi: Expose non-blocking set_variable() wrapper to efivars 

[ Upstream commit 9c6672ac9c ]

Commit 6d80dba1c9 ("efi: Provide a non-blocking SetVariable()
operation") implemented a non-blocking alternative for the UEFI
SetVariable() invocation performed by efivars, since it may
occur in atomic context. However, this version of the function
was never exposed via the efivars struct, so the non-blocking
versions was not actually callable. Fix that.
