staging: rtl8723bs: Cleanups for rtw_inc_and_chk_continual_io_error

There's a warning when using checkpatch.pl check rtw_io.c:

    WARNING: Missing a blank line after declarations
    146: FILE: drivers/staging/rtl8723bs/core/rtw_io.c:146:
    int value = atomic_inc_return(&dvobj->continual_io_error);
    if (value > MAX_CONTINUAL_IO_ERR)

The patch fixes it.

In addition, also rename 'value' variable to 'error_count' and drop
'ret' variable.
