Alexander Aring b743612c0a lockd: don't call vfs_lock_file() for pending requests ...

This patch returns nlm_lck_blocked in nlmsvc_lock() when an asynchronous
lock request is pending. During testing I ran into the case with the
side-effects that lockd is waiting for only one lm_grant() callback
because it's already part of the nlm_blocked list. If another
asynchronous for the same nlm_block is triggered two lm_grant()
callbacks will occur but lockd was only waiting for one.

To avoid any change of existing users this handling will only being made
when export_op_support_safe_async_lock() returns true.
