Subject: ext4: fix check of dqget() return value in ext4_ioctl_setproject()
From: Seth Forshee <seth.forshee@xxxxxxxxxxxxx>
commit ff0bc08454917964291f72ee5b8eca66de4bc250 upstream.
A failed call to dqget() returns an ERR_PTR() and not null. Fix
the check in ext4_ioctl_setproject() to handle this correctly.
Fixes: 9b7365fc1c82 ("ext4: add FS_IOC_FSSETXATTR/FS_IOC_FSGETXATTR interface support")
