Anup Patel 9dc95021db lib: More improvements to sbi_fifo ...

This patch does following improvements to sbi_fifo:
1. Use valid SBI_Exxxx error codes instead of -1
2. The sbi_fifo_is_full() and sbi_fifo_is_empty() did
   not acquire qlock before accessing head and tail
   hence fixed it
3. Added avail member for ease in debugging and simplifying
   head/tail updates.

Due to above changes size of sbi_fifo changes from 48 bytes
to 56 bytes.
