checkpatch: Fix regexp for if, while, etc inside macros.

This allows to use a one-character expression inside the 'if'
statement and multiple spaces before the line continuation character.

Fixes false positive in case like this:

  #define MACRO(ARG)     \
      if (a) {           \
          do_work(ARG);  \
      }
