lockmgr - Fix bug in lockmgr() cancel path
* Fix a bug in the lockmgr() cancel path where a cancelable blocked
exclusive lock is not canceled. The EXREQ2 bit must be tested in
addition to EXREQ, as it is possible for EXREQ to be clear when
EXREQ2 is set.
* Fixes a situation where the usb path could deadlock a softclock
cpu thread, causing a cascade of issues on that cpu.
