staging: rtl8188eu: remove all DBG_88E calls from os_dep/os_intfs.c

Remove all DBG_88E calls from os_dep/os_intfs.c as this macro is
unnecessary, and many of these calls are dubious in terms of necessity.
Removing all calls will ultimately allow the removal of the macro
itself. Also remove variable declarations for variables which now go
unused as a result of this change with os_dep/os_intfs.c
