[PATCH 5.10 127/171] SUNRPC: Handle ENOMEM in call_transmit_status()

[Greg Kroah-Hartman]

From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

[ Upstream commit d3c15033b240767d0287f1c4a529cbbe2d5ded8a ]

Both call_transmit() and call_bc_transmit() can now return ENOMEM, so
let's make sure that we handle the errors gracefully.

Fixes: 0472e4766049 ("SUNRPC: Convert socket page send code to use iov_iter()")
