Zhang Xiaoxu 0cd303aad2 orangefs: Fix kmemleak in orangefs_{kernel,client}_debug_init() 
[ Upstream commit 31720a2b10 ]

When insert and remove the orangefs module, there are memory leaked
as below:

unreferenced object 0xffff88816b0cc000 (size 2048):
  comm "insmod", pid 783, jiffies 4294813439 (age 65.512s)
  hex dump (first 32 bytes):

    [<00000000f11c03c7>] entry_SYSCALL_64_after_hwframe+0x46/0xb0

Use the golbal variable as the buffer rather than dynamic allocate to
slove the problem.
