[PATCH] wan: dscc4: fix build warning Wunused-but-set-variable

[Nicholas Mc Guire]

Fix:
drivers/net/wan/dscc4.c: In function 'dscc4_open':
drivers/net/wan/dscc4.c:1049:25: warning: variable 'ppriv' set but not used
[-Wunused-but-set-variable]

This has been in there unused since 1da177e4c3f (Linux-2.6.12-rc2) simply
remove it.

Was not able to trace when this got put in and why - but if nobody noticed
this within 10 years it probably really is dead code.

Patch was compile tested with x86_64_defconfig + CONFIG_WAN=y
CONFIG_HDLC=m, CONFIG_DSCC4=m

Patch is against 4.1-rc6 (localversion-next is -next-20150605)
