Outstanding mailbox commands, have no way to recover on f/w hung, and we
timeout on waiting for mbx response. This in turn affects the recovery process
as follows:
 - We might already be in dpc while waiting for mbx to complete, so recovery for
   that pci function will never get invoked. Reset Timeout (10 sec) is far less
   than mbx timeout (30 sec).
 - Other mbx cmds will get stuck due to serial mbx access.

Solution is to identify fw-hung scenario and handle outstanding mbx commands to
have an early-exit instead of waiting for response.
Other mbx commands waiting for access will also do an early-exit if fw-hung is
still applicable.

Also, changed boundary checking from size of total
structure to verification that we received the amount of
data needed to cache inernally. This change will provide
compatibility with mbx_sys_info structure sizes in both
older and newer firmware versions.
