[PATCH] libertas: make the hex dumper nicer

Currently, when you define LBS_DEB_HEX, you get every hex dump in the
whole driver, e.g. for LBS_DEB_CMD, LBS_DEB_RX, LBS_DEB_TX etc. This
patch makes sure that you only get the hexdump that you're interested in.

Renamed lbs_dbg_hex() into lbs_deb_hex(), like the other lbs_deb_XXX()
macros.

Made lbs_deb_hex() issue a line feed (and a new prompt) after 16 bytes.

As lbs_deb_hex() now prints the ":" after the prompt by itself, removed
the misc colons in the various *.c files.

lbs_deb_XXX() now print the debug category as well.

As lbs_deb_XXX() --- and especially lbs_deb_11d() --- now print the
category, I removed various "11D:" prefixes in 11d.c as well.
