Since active_mask is first assigned in an "else" block, the compiler throws
a warning saying that the active_mask variable may be used uninitialized in
a print statement later.  Initialize active_mask to 0 in the declaration to
stop the warning.

The code is changed to support the new dynamic logging infrastructure.
Following are the levels added.
Default is 0 - no logging.  0x40000000 - Module Init & Probe.
0x20000000 - Mailbox Cmnds. 0x10000000 - Device Discovery.
0x08000000 - IO tracing.    0x04000000 - DPC Thread.
0x02000000 - Async events.  0x01000000 - Timer routines.
0x00800000 - User space.    0x00400000 - Task Management.
0x00200000 - AER/EEH.       0x00100000 - Multi Q.
0x00080000 - P3P Specific.  0x00040000 - Virtual Port.
0x00020000 - Buffer Dump.   0x00010000 - Misc.
0x7fffffff - For enabling all logs, can be too many logs.

Setting ql2xextended_error_logging module parameter to any of the above
value, will enable the debug for that particular level.
Do LOGICAL OR of the value to enable more than one level.

The additional increment of dsd_seg was causing the compiler to throw an array

cmd_pkt->fcp_data_dseg_len so that the compiler doesn't generate an array out

Support is added for quiescence mode. This feature is for P3P
adapters. Any of the functions can put the firmware into quiescence
state. All the others have to ack that request. During quiescence mode
current commands are processed and all the new incoming I/Os are
blocked. Loop resync is performed after firmware comes out of
quiescence state.
