fs: sysfs: return EGBIG on write if offset is larger than file size
According to the user expectations common utilities like dd or sh
redirection operator > should work correctly over binary files from
sysfs. At the moment doing excessive write can not be completed:
write(1, "\0\0\0\0\0\0\0\0", 8) = 4
write(1, "\0\0\0\0", 4) = 0
write(1, "\0\0\0\0", 4) = 0
write(1, "\0\0\0\0", 4) = 0
...
Fix the problem by returning EFBIG described in man 2 write.
