Subject: [PATCH -next 2/2] ipw2x00: remove set but not used variable 'force_update'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/wireless/intel/ipw2x00/ipw2100.c: In function shim__set_security:
drivers/net/wireless/intel/ipw2x00/ipw2100.c:5582:9: warning: variable force_update set but not used [-Wunused-but-set-variable]

It is introduced by commit 367a1092b555 ("ipw2x00:
move under intel vendor directory"), but never used, so remove it.
