efi: Expose non-blocking set_variable() wrapper to efivars
commit 9c6672ac9c91f7eb1ec436be1442b8c26d098e55 upstream.
Commit 6d80dba1c9fe ("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.
