staging: rtlwifi: Remove set but not used variables 'dataempty, hoffset'

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

drivers/staging/rtlwifi/efuse.c: In function 'efuse_pg_packet_write':
drivers/staging/rtlwifi/efuse.c:922:24: warning:
 variable 'dataempty' set but not used [-Wunused-but-set-variable]

drivers/staging/rtlwifi/efuse.c: In function 'efuse_get_current_size':
drivers/staging/rtlwifi/efuse.c:1185:5: warning:
 variable 'hoffset' set but not used [-Wunused-but-set-variable]

They're never used and can be removed.
