[PATCH 5/9] acpi: gpedump: remove redundant store to gpe_xrupt_info

[Colin King]

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

Static analysis from clang scan-build detected a redundant
store to gpe_xrupt_info.  Remove this and restructure the
for loops into while loops to make the code a little easier
to read.
