Modify UEFI anti-bricking code

[Luis Henriques]

Ubuntu kernels have already been SRU'ed (bug #1040557) to mitigate the problem of UEFI machines being bricked by nvram being filled up. However, this problem is still present and a recent upstream fix has been accepted in mainline:

f8b8404337de4e2466e2e1139ea68b1f8295974f Modify UEFI anti-bricking code

This fix should be backported to Ubuntu kernels, starting with Precise.
