locks: Handle negative values for flock->l_len
As per 'man 3 fcntl',
"If l_len is positive, the area affected shall start at
l_start and end at l_start+l_len−1. If l_len is negative,
the area affected shall start at l_start+l_len and end at
l_start−1. Locks may start and extend beyond the current
end of a file, but shall not extend before the beginning
of the file."
Currently we return EINVAL if l_len is found to be negative.
Fixed the same as mentioned in the man page.
This is backport of the below patch
