[PATCH] staging: cxt1e1: Fix static symbol sparse warnings for global vars in linux.c

[Jeff Oczek <jeffoczek@gmail.com>]

Put extern declarations in cxt1e1_common.h to reduce sparse warnings for linux.c:
drivers/staging/cxt1e1/linux.c:86:13: warning:
  symbol 'error_flag' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:91:13: warning:
  symbol 'cxt1e1_max_mru' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:95:13: warning:
  symbol 'cxt1e1_max_mtu' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:96:13: warning:
  symbol 'max_mtu_default' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:99:13: warning:
  symbol 'max_txdesc_used' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:100:13: warning:
  symbol 'max_txd:esc_default' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:103:13: warning:
  symbol 'max_rxdesc_used' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:104:13: warning:
  symbol 'max_rxdesc_default' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:153:1: warning:
  symbol 'c4_wk_chan_restart' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:171:1: warning:
  symbol 'c4_wk_chan_init' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:186:1: warning:
  symbol 'c4_wq_port_init' was not declared. Should it be static?
drivers/staging/cxt1e1/linux.c:208:1: warning:
