Revert "indentation fix with uncrustify"

This reverts commit 8ebe53b2809bc201c56c119a0f67e7167c3b51d4.
misc cosmetic changes
Get rid of some pointless return value indirections.
Do not initialize pointers to 0.

NOTE: There are probably more, please doublecheck.
Replace a memset(0) with a zero initialization.
Drop some unnecessary variable initializations.
Drop one level of pointer indirection in qsv_decode_init().
Clean up #includes for qsv_h264.h.
Add missing parameter names to function declarations.
Switch conditional expressions to more common libav style.
Avoid one variable indirection in ff_qsv_mem_buffer_alloc().
