staging: rtl8822be: Keep array subscript no lower than zero

Browse source

The kbuild test robot reports the following:
   drivers/staging//rtlwifi/phydm/phydm_dig.c: In function 'odm_pause_dig':
   drivers/staging//rtlwifi/phydm/phydm_dig.c:494:45: warning: array subscript is below array bounds [-Warray-bounds]
      odm_write_dig(dm, dig_tab->pause_dig_value[max_level]);

This condition is caused when a loop falls through. The fix is to pin
max_level to be >= 0.
