media: staging: tegra-vde: print long unsigned using %lu format specifier

The frame.flags & FLAG_B_FRAME is promoted to a long unsigned because
of the use of the BIT() macro when defining FLAG_B_FRAME and causing a
build warning. Fix this by using the %lu format specifer.

Cleans up warning:
drivers/staging/media/tegra-vde/tegra-vde.c:267:5: warning: format
specifies type 'int' but the argument has type 'unsigned long' [-Wformat]
