LINUX: Fix osi_proc.c formatting

LINUX: Fix osi_proc.c formatting

osi_proc.c had a few formatting issues:

 - Several function definitions did not have the function name at the
   beginning of the line

 - A few preprocessor directives were not indented

 - A few areas used a tab character for each indentation level, as
   opposed to 4 spaces, then 1 tab, as the rest of the tree has

 - Struct definitions were aligned using tabs, not spaces, causing
   misalignments when the indentation was fixed

Fix these.
