mutex: Drop linkage.h from mutex.h

<linux/mutex.h> does not use nor need <linux/linkage.h>, so drop that
one header file from mutex.h.

<linux/mutex.h> is currently #included in around 1250 C source files
(oops, I didn't count other header files that #include it), making it
the 27th most-used header file.

Build tested on i386 and x86_64 * (allnoconfig, tiny.config, defconfig,
allyesconfig, and allmodconfig) and x64_64 allmodconfig + SMP=disabled.
