btrfs: implement btrfs_debug* in terms of helper macro
First, the btrfs_debug macros open-code (one possible definition of)
DYNAMIC_DEBUG_BRANCH, so they don't benefit from the CONFIG_JUMP_LABEL
optimization.
Second, a planned change of struct _ddebug (to reduce its size on 64 bit
machines) requires that all descriptors in a translation unit use
distinct identifiers.
Using the new _dynamic_func_call_no_desc helper macro from
dynamic_debug.h takes care of both of these. No functional change.
