[PATCH] [MTD] UBI: fix background thread define

[Alexander Schmidt <alexs@linux.vnet.ibm.com>]

Hi Artem,

This patch renames DBG_ENABLE_BGT to DBG_DISABLE_BGT, which makes it more
obvious that the background thread should be enabled by default. The name
corresponds to the kernel config option now.

I also fixed the semantics on intialisation (bgt now gets enabled when
DBG_DISABLE_BGT == 0), and compilation with debugging disabled works again.
