mwifiex: don't disable hardirqs; just softirqs

main_proc_lock and int_lock (in mwifiex_adapter) are the only spinlocks
used in hardirq contexts. The rest are only in task or softirq contexts.

Convert every other lock from *_irq{save,restore}() variants to _bh()
variants.

This is a mechanical transformation of all spinlock usage in mwifiex
using the following:

Step 1:
I ran this nasty sed script:

    sed -i -E '/spin_lock_irqsave|spin_unlock_irqrestore/ {
      /main_proc_lock|int_lock/! {
        s:(spin_(un|)lock)_irq(save|restore):\1_bh: ;
        # Join broken lines.
        :a /;$/! {
          N;
          s/\s*\n\s*//;
          ba
        }
        /,.*\);$/ s:,.*\):\):
      }
    }' drivers/net/wireless/marvell/mwifiex/*

Step 2:
Manually delete the flags / ra_list_flags args from:

  mwifiex_send_single_packet()
  mwifiex_11n_aggregate_pkt()
  mwifiex_send_processed_packet()

which are now unused.

Step 3:
Apply this semantic patch (coccinelle) to remove the unused 'flags'
variables:

// <smpl>
@@
type T;
identifier i;
@@

(
extern T i;
|
- T i;
  ... when != i
)
// </smpl>

(Usage is something like this:

  make coccicheck COCCI=./patch.cocci MODE=patch M=drivers/net/wireless/marvell/mwifiex/

although this skips *.h files for some reasons, so I had to massage
stuff.)

Testing: I've played with a variety of stress tests, including download
stress tests on the same APs which caught regressions with commit
5188d5453bc9 ("mwifiex: restructure rx_reorder_tbl_lock usage"). I've
primarily tested on Marvell 8997 / PCIe, although I've given 8897 / SDIO
a quick spin as well.
