Vladimir Zapolskiy 818e100c2b phy: qcom-qusb2: Fix a memory leak on probe 
[ Upstream commit bf7ffcd0069d30e2e7ba2b827f08c89f471cd1f3 ]

On success nvmem_cell_read() returns a pointer to a dynamically allocated
buffer, and therefore it shall be freed after usage.

The issue is reported by kmemleak:

  # cat /sys/kernel/debug/kmemleak
  unreferenced object 0xffff3b3803e4b280 (size 128):
    comm "kworker/u16:1", pid 107, jiffies 4294892861 (age 94.120s)
