media: dvbdev: Use %pe format specifier

Browse Source 
The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR()

This patch fixes this cocci report:
./dvb-core/dvbdev.c:575:48-55: WARNING: Consider using %pe to print PTR_ERR()
