Subject: [PATCH v2] staging: qlge: emit debug and dump at same level

Write a macro QLGE_DUMP_DBG having a function print_hex_dump so that
the debug and dump are emitted at the same KERN_<LEVEL> and code becomes
simpler. Write a macro instead of calling the function directly in
ql_mpi_core_to_log() to go according to the coding practices followed in
other drivers such as nvec and vc04_services.

changes since v1: make code of ql_mpi_core_to_log() simpler.
