Subject: [PATCH] Staging: rtl8192e: remove set but not used variable 'tmpRegC'

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

drivers/staging/rtl8192e/rtl8192e/r8192E_dev.c: In function rtl92e_start_adapter:
drivers/staging/rtl8192e/rtl8192e/r8192E_dev.c:693:15: warning: variable ‘tmpRegC’ set but not used [-Wunused-but-set-variable]

commit 94a799425eee ("rtl8192e: Split into two directories")
involved this, remove it.
