Suppress undefined rwreset error in obmc-flash-bmc

This commit tweaks obmc-flash-bmc to suppress the error message
produced when the environment variable rwreset is undefined. In
context, this variable is checked to verify if a factory reset
should be performed. If the variable is not set, or if it's set
to anything other than true, we don't perform the reset - this is
not an error, so no need to log one to the journal.

Resolves openbmc/openbmc#2249
