Description

otherwise it's possible to get -EBADF:

client sends open|create intent before a connection to OST is established
MDS replies back without UPDATE bit in LDLM lock, but with the layout
(MDS doesn't send OBD_MD_FLMODEASIZE and back
client's cl_default_mds_easize is still 0
client sends getattr intent with 0-size buffer for EA
MDS replies with no layout and LAYOUT bit
client sets local layout to EMPTY
all subsequent I/O fails with -EBADF
