Gabriel Krisman Bertazi 21b81716c6 ipr: Fix regression when loading firmware ...

Commit d63c7dd5bc ("ipr: Fix out-of-bounds null overwrite") removed
the end of line handling when storing the update_fw sysfs attribute.
This changed the userpace API because it started refusing writes
terminated by a line feed, which broke the update tools we already have.

This patch re-adds that handling, so both a write terminated by a line
feed or not can make it through with the update.
