Add missing error checks for FileDescription.Init.
Syzkaller discovered this bug in pipefs by doing something quite strange:
creat(&(0x7f0000002a00)='./file1\x00', 0x0)
mount(&(0x7f0000000440)=ANY=[], &(0x7f00000002c0)='./file1\x00', &(0x7f0000000300)='devtmpfs\x00', 0x20000d, 0x0)
creat(&(0x7f0000000000)='./file1/file0\x00', 0x0)
This can be reproduced with:
touch mymount
mkfifo /dev/mypipe
mount -o ro -t devtmpfs devtmpfs mymount
echo 123 > mymount/mypipe
