Robert Elliott 432f16e64f fs: clarify rate limit suppressed buffer I/O errors 
When quiet_error applies rate limiting to buffer_io_error calls, what the
they apply to is unclear because the name is so generic, particularly
if the messages are interleaved with others:

[ 1936.063572] quiet_error: 664293 callbacks suppressed
[ 1936.065297] Buffer I/O error on dev sdr, logical block 257429952, lost async page write
[ 1936.067814] Buffer I/O error on dev sdr, logical block 257429953, lost async page write

Also, the function uses printk_ratelimit(), although printk.h includes a
comment advising "Please don't use... Instead use printk_ratelimited()."

Change buffer_io_error to check the BH_Quiet bit itself, drop the
printk_ratelimit call, and print using printk_ratelimited.

This makes the messages look like:

[  387.208839] buffer_io_error: 676394 callbacks suppressed
[  387.210693] Buffer I/O error on dev sdr, logical block 211291776, lost async page write
[  387.213432] Buffer I/O error on dev sdr, logical block 211291777, lost async page write
