module: move __module_get and try_module_get() out of line.
With the preempt, tracepoint and everything, it's getting a bit
chubby. For an Ubuntu-based config:
Before:
$ size -t `find * -name '*.ko'` | grep TOTAL
56199906 3870760 1606616 61677282 3ad1ee2 (TOTALS)
$ size vmlinux
text data bss dec hex filename
8509342 850368 3358720 12718430 c2115e vmlinux
After:
$ size -t `find * -name '*.ko'` | grep TOTAL
56183760 3867892 1606616 61658268 3acd49c (TOTALS)
$ size vmlinux
text data bss dec hex filename
8501842 849088 3358720 12709650 c1ef12 vmlinux
