[PATCH v4 1/2] ALSA: core: remove initialise static variables to 0

[Meng Tang <tangmeng@uniontech.com>]

Initializing the static variable to 0 causes the following error
when exec checkpatch:

ERROR: do not initialise statics to 0
FILE: sound/sound_core.c:142:
static int preclaim_oss = 0;

In addition, considering the following way of writing
139: #ifdef config_sound_oss_core_preclaim
140: Static int preclaim_oss = 1;
141: #ELSE
142: Static int preclaim_oss = 0;
143: #ENDIF
We can optimize it by IS_ENABLED(CONFIG_SOUND_OSS_CORE_PRECLAIM),
so modified it to
static int preclaim_oss = IS_ENABLED(CONFIG_SOUND_OSS_CORE_PRECLAIM);
