David Edmondson 797e3e3805 block: report errno when flock fcntl fails
When a call to fcntl(2) for the purpose of adding file locks fails
with an error other than EAGAIN or EACCES, report the error returned
by fcntl.

EAGAIN or EACCES are elided as they are considered to be common
failures, indicating that a conflicting lock is held by another
process.

No errors are elided when removing file locks.
