linux_mtd: Free param right after its last usage

Param is only used in the first half of init function, and it is
local, so there is no need to keep it until the end. This makes
handling error paths in the second half of init function shorter,
because those paths can just return 1 instead of going to a label.

BUG=b:185191942
TEST=builds and ninja test from CB:56413
