kernel/locking: Fix compile error with qrwlock.c

Saw these compile errors on SPARC when queued rwlock feature is enabled.

 CC      kernel/locking/qrwlock.o
kernel/locking/qrwlock.c: In function ‘queued_read_lock_slowpath’:
kernel/locking/qrwlock.c:89: error: implicit declaration of function ‘arch_spin_lock’
kernel/locking/qrwlock.c:102: error: implicit declaration of function ‘arch_spin_unlock’
make[4]: *** [kernel/locking/qrwlock.o] Error 1

Include spinlock.h in qrwlock.c to fix it.
