Series [PULL,01/12] virtiofsd: Fix side-effect in assert() | expand

Commit Message

From: Mahmoud Mandour <ma.mandourr@gmail.com>

Replaced the allocation of local variables from malloc() to
GLib allocation functions.

In one instance, dropped the usage to an assert after a malloc()
call and used g_malloc() instead.
