    sys/vfs/fuse: Drop PCATCH from tsleep on waiting IPC completion
    
    Even with kern_sigprocmask(SIG_BLOCK) called prior to tsleep(9),
    tsleep with PCATCH flag can still catch a signal (e.g. SIGINT) and
    return 0 (not EINTR).
    
    This is due to tsleep(9) setting "lp->lwp_flags |= LWP_SINTR;" before
    going into sleep when PCATCH is specified.
    
    When this happens, KKASSERT() after tsleep(9) can be false, so just
    drop PCATCH.
