staging: rtl8712: hal_init.c: Remove leading p from variable names 

Remove the leading p from the following pointer variable names:
- padapter
- pusb_intf
- ppmappedfw
- praw
- pfwpriv
- pdvobj
- pregpriv
- pmappedfw (not in the same scope as ppmappedfw)
- ptmpchar
- ppayload
- ptx_desc
Issue found with Coccinelle.
