Subject[PATCH 9/9] efivars: Call guid_parse() against guid_t type of variable
Date
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

uuid_le_to_bin() is deprecated API and take into consideration that variable,
to where we store parsed data, is type of guid_t we switch to guid_parse()
for sake of consistency.

While here, add error checking to it.
