um: Use RWSEM_GENERIC_SPINLOCK on x86

commit 3a3679078aed2c451ebc32836bbd3b8219a65e01 upstream.

Commit d12337 (rwsem: Remove redundant asmregparm annotation)
broke rwsem on UML.

As we cannot compile UML with -mregparm=3 and keeping asmregparm only
for UML is inadequate the easiest solution is using RWSEM_GENERIC_SPINLOCK.

Thanks to Thomas Gleixner for the idea.
