obmc-flash-bmc: Ignore error if rwfs_size is not set

Ignore the return code of fw_printenv in case rwfs_size doesn't
exist, otherwise the function fails and doesn't get set.
Also check that the imgsize variable is set before calling
fw_setenv to prevent accidentally clearing the rwfs_size.

Tested: Verified that rwfs_size gets set when it didn't exist.
Also that it gets updated when the value is different than
the one passed. And that it doesn't get cleared if the function
is called without passing the imgsize argument.
