Subject: ARCv2: fix local_save_flags

From: Vineet Gupta <vgupta@synopsys.com>

commit cd5d38b052384daa2893e9a1d94900d5a20ed4b5 upstream.

Commit d9676fa152c83b ("ARCv2: Enable LOCKDEP"), changed
local_save_flags() to not return raw STATUS32 but encoded in the form
such that it could be fed directly to CLRI/SETI instructions.
However the STATUS32.E[] was not captured correctly as it corresponds to
bits [4:1] in the register and not [3:0]
