Brooks Davis f95509a489 mdmfs: Fix many bugs in automatic md(4) creation.
This code allocated a correctly sized buffer, read past the end of the
source buffer, writing off the end of the target buffer, and then writing
a '\0' terminator past the end of the target buffer (in the wrong place).
It then leaked the buffer.

Switch to a statically sized buffer on the stack and update the source
pointer and
length before use so the correct things are copied.

Fix a logic error in the checks that the format of the line is as
expected and move on out of an assert.

Remove an unneeded close(). fclose() closes the descriptor.
