jiffies: Force inlining of {m,u}msecs_to_jiffies()

With this config:

  http://busybox.net/~vda/kernel_config_OPTIMIZE_INLINING_and_Os

gcc-4.7.2 generates many copies of these tiny functions:

	msecs_to_jiffies (45 copies):
	55                      push   %rbp
	48 89 e5                mov    %rsp,%rbp
	e8 59 ec 03 00          callq  __msecs_to_jiffies
	5d                      pop    %rbp
	c3                      retq

	usecs_to_jiffies (10 copies):
	55                      push   %rbp
	48 89 e5                mov    %rsp,%rbp
	e8 5d 54 5e ff          callq  __usecs_to_jiffies
	5d                      pop    %rbp
	c3                      retq

This patch fixes this via s/inline/__always_inline/
