Ard Biesheuvel 749f3d3aa0 efivarfs: revert "fix memory leak in efivarfs_create()" 
[ Upstream commit ff04f3b6f2 ]

The memory leak addressed by commit fe5186cf12 is a false positive:
all allocations are recorded in a linked list, and freed when the
filesystem is unmounted. This leads to double frees, and as reported
by David, leads to crashes if SLUB is configured to self destruct when
double frees occur.

So drop the redundant kfree() again, and instead, mark the offending
pointer variable so the allocation is ignored by kmemleak.
