[PATCH] staging: rtl8723bs: Remove set but not used variable 'oldcnt'

[zhengbin]

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

drivers/staging/rtl8723bs/hal/sdio_ops.c: In function sdio_read_port:
drivers/staging/rtl8723bs/hal/sdio_ops.c:430:6: warning: variable oldcnt set but not used [-Wunused-but-set-variable]

It is not used since commit dedf215bd1c7 ("staging:
rtl8723bs: remove unused code")
