gpu: nvgpu: update nvgpu_pte_dbg_print function

Browse Source 
Currently, nvgpu_pte_dbg_print() overwrites ctag string "ctag=" and only
prints ctag number.
For example,
nvgpu_pte_dbg_print:104  [DBG]  vm=3 PTE: i=0    size=8  |
GPU 0x1efc000000  phys 0x115a50000  pgsz:   4kb perm=RW kind=0x8 APT=SYSTEM C--V- 1
[0x08000010, 0x115a5007]

Update nvgpu_pte_dbg_print function to include ctag string.
nvgpu_pte_dbg_print:104  [DBG]  vm=3 PTE: i=0    size=8  |
GPU 0x1efc000000  phys 0x115a50000  pgsz:   4kb perm=RW kind=0x8 APT=SYSTEM C--V- ctag=1
[0x08000010, 0x115a5007]
