linuxthreads.old: fix set-but-unused warning

Move spin_count down to the code block where it's used to fix the warning:

libpthread/linuxthreads.old/spinlock.c: In function '__pthread_lock':
libpthread/linuxthreads.old/spinlock.c:70:7: warning:
	variable 'spin_count' set but not used [-Wunused-but-set-variable]
