PNP: isapnp: remove set but not used variable 'checksum'
Fixes gcc '-Wunused-but-set-variable' warning: drivers/pnp/isapnp/core.c: In function ‘isapnp_build_device_list’: drivers/pnp/isapnp/core.c:777:27: warning: variable ‘checksum’ set but not used [-Wunused-but-set-variable] It is never used, and so can be removed.
