We really don't care about triggering buffer errors for this condition.
This avoids a spew of:

Buffer I/O error on dev sdc, logical block 785929, async page read
Buffer I/O error on dev sdc, logical block 759095, async page read
Buffer I/O error on dev sdc, logical block 766922, async page read
Buffer I/O error on dev sdc, logical block 17659, async page read
Buffer I/O error on dev sdc, logical block 637571, async page read
Buffer I/O error on dev sdc, logical block 39241, async page read
Buffer I/O error on dev sdc, logical block 397241, async page read
Buffer I/O error on dev sdc, logical block 763992, async page read

from -EAGAIN conditions on request allocation for async reads.
