liblzma: CRC: Remove crc_always_inline, use lzma_always_inline instead.

Now crc_simd_body() in crc_x86_clmul.h is only called once
in a translation unit, we no longer need to be so cautious
about ensuring the always-inline behavior.

-// The inline keyword is only a suggestion to the compiler to substitute the
-// body of the function into the places where it is called. If a function
-// is large and called multiple times then compiler may choose to ignore the
-// inline suggestion at a sometimes high performance cost.
-//
-// MSVC's __forceinline is a keyword that should be used in place of inline.
-// If both __forceinline and inline are used, MSVC will issue a warning.
-// Since MSVC's keyword is a replacement keyword, the lzma_always_inline
-// macro must also contain the inline keyword when its not used in MSVC.
-//
-// NOTE: This doesn't use lzma_always_inline for now as support for it is
-// detected using preprocessor macros which might miss a compiler that
-// does support it. All compilers that support the CLMUL code support
-// the attribute too; if not, we will hopefully get a bug report.
