checkpatch: improve space before tab --fix option
This test should remove all the spaces before a tab not just one space. Substitute a tab for each 8 space block before a tab and remove less than 8 spaces before a tab. This SPACE_BEFORE_TAB test is done after CODE_INDENT. If there are spaces used at the beginning of a line that should be converted to tabs, please make sure that the CODE_INDENT test and conversion is done before this SPACE_BEFORE_TAB test and conversion.
