arch/x86/include/asm/fixmap.h: mark __set_fixmap_offset as __always_inline 

When compiling arch/x86/kernel/early_printk_mrst.c with i386
allmodconfig, gcc-4.1.0 generates an out-of-line copy of
__set_fixmap_offset() which contains a reference to
__this_fixmap_does_not_exist which the compiler cannot elide.

Marking __set_fixmap_offset() as __always_inline prevents this.
