[PATCH] lib: fwts_cmos: remove cli/sti assembler from cmos reading

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Recent Linux kernel config defaults will not allow messing around with
the interrupt disable/enable from userspace and will segfault the code.
Remove these as they don't really need to be used and we just need to
remember that updates to CMOS data may occur under kernel control
while it is being read by fwts.
