    powerpc/kernel: Fix FP and vector register restoration
    
    Currently tsk->thread->load_vec and load_fp are not initialized during
    task creation, which can lead to garbage values in these variables (non-zero
    values).
    
    These variables will be checked later in restore_math() to validate if the
    FP and vector registers are being utilized. Since these values might be
    non-zero, the restore_math() will continue to save the FP and vectors even if
    they were never utilized by the userspace application. load_fp and load_vec
    counters will then overflow (they wrap at 255) and the FP and Altivec will be
    finally disabled, but before that condition is reached (counter overflow)
    several context switches will have restored FP and vector registers without
    need, causing a performance degradation.
    
    Fixes: 70fe3d980f5f ("powerpc: Restore FPU/VEC/VSX if previously used")
