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.
