Meanwhile it cleans up the code, the behaviour is slightly changed. In case of
providing non-boolean value it will fails with corresponding error. In the
original code the attempt of an update was just ignored in such case.

This patch converts custom dumper to use native print_hex_dump() instead. The
cifs_dump_mem() will have an offsets per each line which differs it from the
original code.
In the dump_smb() we may use native print_hex_dump() as well. It will show
slightly different output in ASCII part when character is unprintable,
otherwise it keeps same structure.

The useful macros embed message level in the name. Thus, it cleans up the code
a bit. In cases when it was plain printk() the conversion was done to info
level.
